> I've been stress testing DocumentsWriter by indexing wikipedia, but not
> giving enough memory to the JVM, in varying heap sizes to tickle the
> different interesting cases.  Sometimes DocumentsWriter can deadlock;
> other times it will hit a subsequent NPE or AIOOBE or assertion
> failure.
> I've fixed all the cases I've found, and added some more asserts.  Now
> it just produces plain OOM exceptions.  All changes are contained to
> DocumentsWriter.java.
> All tests pass.  I plan to commit in a day or two!
