Thanks - I will check out the patch.
I understand that MVCC will eliminate Read Conflicts and is scheduled for Zope 2.8 which will be in alpha any day now.
Is there a patch available right now to use MVCC in 2.7.X?
Yes and no. Yes: I believe Dieter Maurer has implemented a flavor of MVCC for the ZODB that ships with Zope 2.7 (although I'm not quite sure where to find it). No: the MVCC implementation that will ship with Zope 2.8 cannot be used with Zope 2.7 because it depends on bits that depend on being able to pickle new-style Python classes, which the ZODB that ships with Zope 2.7 cannot do. - C
