Should be, although I just realized I don't know whether 0.0.2 was
intended for Zope 2.2 or 2.3.

Ugh.  I have no idea what might have happened.  That's why I'm wary: if
something goes wrong, the symptoms will show up a long time after the
problems occur.

Now BerkeleyStorage is on its way and once that's ready,
PartitionedFileStorage will have such a small audience that it won't be
worth the trouble.  Oh well, it was a fun experiment.
