Agreed, that sounds like a good option.

In my previous email I had forgotten about the DB_PRIVATE flag to
DBEnv objects; that prevents them from writing extra DBEnv files to the
filesystem for use when multi-process access is not needed.

I just committed the small change needed to bsddb/__init__.py for it to
use a DBEnv allowing multithreaded access.  The original hammer.py from
bug 775414 has been running for 15 minutes without problems on my alpha
with BerkeleyDB 4.1.25.
