---------------------------------------------

Oh 2012, how we missed you. Apparently this is still an issue! We should probably fix it.

> The uncaught exception handler registered in NIOServerCnxnFactory and ClientCnxn simply logs exceptions and lets the rest of ZooKeeper go on its merry way.  However, errors such as OutOfMemoryErrors should really crash the program, as they represent unrecoverable errors.  If the exception that gets to the uncaught exception handler is an instanceof a java.lang.Error, ZK should exit with an error code (in addition to logging the error).
