I think after provide transaction isolation for the duration of an
error, we will not see this symptom occur again.  That's the first step,
at least.  We are going to have a "bugathon" at the Zope 2 sprint at
PyCon 9 days from now, and I will put this high on the list.  Would you
be willing to test a Zope 2.7 version that contains a fix?

Thanks!
