Sorry, I haven't been following this thread, but I will note that I've seen 
(repeatably) in my test Zope environment this behaviour.

This is probably unrelated though...

For me, the situation comes about when I am loading up my fresh (ie. clean 
ZODB) test Zope with a thousand users. While the load script is running (it 
runs on the command-line and goes TTW using urllib to register the users) if 
I access a page which summarises all users, I *sometimes* get None for some 
of the users. The page uses a Catalog to find basic user info, and sometimes 
uses getObject() to find the real user object. The getObject() appears to 
return None sometimes.

Once the load is complete, I don't see any errors. So I blame some mechanism 
failing under load. I also often see ReadConflictErrors, but I understand 
they're going away soon :)
