[Zope] BTreeFolder2 question

[sean.upton@uniontrib.com]

If I understand correctly, I think the likelihood of the same id being
chosen is very low; that said, I think the generateId() method is also
designed to reduce likelihood of conflict errors (though not entirely
eliminate) by having each thread or ZEO client likely writing to different
buckets (thanks to random initial id per thread, plus sequential behavior
afterward for so many ids).

Old message from ZODB-Dev that might be useful (this is pre-BTreeFolder2,
but I think we are discussing the same thing).

Hello, zope users!

BTreeFolder2 has generateId method, what will be if two or more  zeo 
clients try to
to write to the same folder at the same time, will be uniqueness of ids 
guaranted?

Thanks in advance
