The fix for https://bugs.launchpad.net/zodb/+bug/509801 hasn't been backported to 3.9, although I assume it could be. Do you know that Zope 2.10 won't work with ZODB 3.9?

The hardest part would be resisting the temptation to backport other fixes. :) I'll look at making a 3.8 release with just this, or maybe this and a few other fixes if they are extremely low-hanging.
