-/**
- * Base class for simple,  small classes 
- * maintaining single values that are always accessed
- * and updated under synchronization. Since defining them for only
- * some types seemed too arbitrary, they exist for all basic types,
- * although it is hard to imagine uses for some.
- * <p>
- *   These classes mainly exist so that you do not have to go to the
- *   trouble of writing your own miscellaneous classes and methods
- *   in situations  including:
- *  <ul>
- *   <li> When  you need or want to offload an instance 
- *    variable to use its own synchronization lock.
- *    When these objects are used to replace instance variables, they
- *    should almost always be declared as <code>final</code>. This
- *    helps avoid the need to synchronize just to obtain the reference
- *    to the synchronized variable itself.
- *
- *    <li> When you need methods such as set, commit, or swap.
- *    Note however that
- *    the synchronization for these variables is <em>independent</em>
- *    of any other synchronization perfromed using other locks. 
- *    So, they are not
- *    normally useful when accesses and updates among 
- *    variables must be coordinated.
- *    For example, it would normally be a bad idea to make
- *    a Point class out of two SynchronizedInts, even those
- *    sharing a lock.
- *
- *    <li> When defining <code>static</code> variables. It almost
- *    always works out better to rely on synchronization internal
- *    to these objects, rather  than class locks.
- *  </ul>
- * <p>
- * While they cannot, by nature, share much code,
- * all of these classes work in the same way.
- * <p>
- * <b>Construction</b> <br>
- * Synchronized variables are always constructed holding an
- * initial value of the associated type. Constructors also
- * establish the lock to use for all methods:
- * <ul>
- *   <li> By default, each variable uses itself as the
- *        synchronization lock. This is the most common
- *        choice in the most common usage contexts in which
- *        SynchronizedVariables are used to split off
- *        synchronization locks for independent attributes
- *        of a class.
- *   <li> You can specify any other Object to use as the
- *        synchronization lock. This allows you to
- *        use various forms of `slave synchronization'. For
- *        example, a variable that is always associated with a
- *        particular object can use that object's lock.
- * </ul>
- * <p>
- * <b>Update methods</b><br>
- * Each class supports several kinds of update methods:
- * <ul>
- *   <li> A <code>set</code> method that sets to a new value and returns 
- *    previous value. For example, for a SynchronizedBoolean b,
- *    <code>boolean old = b.set(true)</code> performs a test-and-set.
- * <p>
- *   <li> A  <code>commit</code> method that sets to new value only
- *    if currently holding a given value.
- * 
- * For example, here is a class that uses an optimistic update
- * loop to recompute a count variable represented as a 
- * SynchronizedInt. 
- *  <pre>
- *  class X {
- *    private final SynchronizedInt count = new SynchronizedInt(0);
- * 
- *    static final int MAX_RETRIES = 1000;
- *
- *    public boolean recomputeCount() throws InterruptedException {
- *      for (int i = 0; i &lt; MAX_RETRIES; ++i) {
- *        int current = count.get();
- *        int next = compute(current);
- *        if (count.commit(current, next))
- *          return true;
- *        else if (Thread.interrupted()) 
- *          throw new InterruptedException();
- *      }
- *      return false;
- *    }
- *    int compute(int l) { ... some kind of computation ...  }
- *  }
- * </pre>
- * <p>
- *   <li>A <code>swap</code> method that atomically swaps with another 
- *    object of the same class using a deadlock-avoidance strategy.
- * <p>
- *    <li> Update-in-place methods appropriate to the type. All
- *    numerical types support:
- *     <ul>
- *       <li> add(x) (equivalent to return value += x)
- *       <li> subtract(x) (equivalent to return value -= x)
- *       <li> multiply(x) (equivalent to return value *= x)
- *       <li> divide(x) (equivalent to return value /= x)
- *     </ul>
- *   Integral types also support:
- *     <ul>
- *       <li> increment() (equivalent to return ++value)
- *       <li> decrement() (equivalent to return --value)
- *     </ul>
- *    Boolean types support:
- *     <ul>
- *       <li> or(x) (equivalent to return value |= x)
- *       <li> and(x) (equivalent to return value &amp;= x)
- *       <li> xor(x) (equivalent to return value ^= x)
- *       <li> complement() (equivalent to return x = !x)
- *     </ul>
- *    These cover most, but not all of the possible operators in Java.
- *    You can add more compute-and-set methods in subclasses. This
- *    is often a good way to avoid the need for ad-hoc synchronized
- *    blocks surrounding expressions.
- *  </ul>
- * <p>
- * <b>Guarded methods</b> <br>
- *   All <code>Waitable</code> subclasses provide notifications on
- *   every value update, and support guarded methods of the form
- *   <code>when</code><em>predicate</em>, that wait until the
- *   predicate hold,  then optionally run any Runnable action
- *   within the lock, and then return. All types support:
- *     <ul>
- *       <li> whenEqual(value, action)
- *       <li> whenNotEqual(value, action)
- *     </ul>
- *   (If the action argument is null, these return immediately
- *   after the predicate holds.)
- *   Numerical types also support 
- *     <ul>
- *       <li> whenLess(value, action)
- *       <li> whenLessEqual(value, action)
- *       <li> whenGreater(value, action)
- *       <li> whenGreaterEqual(value, action)
- *     </ul>
- *   The Waitable classes are not always spectacularly efficient since they
- *   provide notifications on all value changes.  They are
- *   designed for use in contexts where either performance is not an
- *   overriding issue, or where nearly every update releases guarded
- *   waits anyway.
- *  <p>
- * <b>Other methods</b> <br>
- *   This class implements Executor, and provides an <code>execute</code>
- *   method that runs the runnable within the lock.
- *   <p>
- *   All classes except SynchronizedRef and WaitableRef implement
- *   <code>Cloneable</code> and <code>Comparable</code>.
- *   Implementations of the corresponding
- *   methods either use default mechanics, or use methods that closely
- *   correspond to their java.lang analogs. SynchronizedRef does not
- *   implement any of these standard interfaces because there are
- *   many cases where it would not make sense. However, you can
- *   easily make simple subclasses that add the appropriate declarations.
- *
