Comment added by Karl Wright:

I'm not sure what yet the problem might be under PostgreSQL - I haven't yet tried that.
However, I did try to do a performance run under Derby.  Derby runs well for a time but then
stalls - it seems to wind up with that same internal deadlock I coded around before.  It doesn't
error out at that point anymore, but since it stalls for an entire minute before it detects
the deadlock, you lose a lot of time and performance as a result.

I'm not quite sure what to do about about this issue with Derby.  Maybe I can lower the deadlock
timeout threshold; I'll have to think about that for a while.  I'll look at PostgreSQL next.

In reply to a comment by Karl Wright:
I will try to run a new batch of performance tests tonight or tomorrow, and get back to you
either way.
