Is "shelve" thread-safe on Windows?

I see a bsddb.pyd included with Python 1.5.1, and I assume with 1.5.2.  I
think this means Python shouldn't fall back to dumbdbm on a normal
installation.  If I am wrong about that, e.g. if bsddbm.pyd is based on the
1.x series dbm that didn't support concurrent use, I think you can get a
safe version of dbm from www.SleepyCat.com, or maybe the gdbm from
www.roth.net/libs.  It should be quite simple to plug in one of those to the
bsddbm or gdbm Python module source.
