That's nice though not immediately helpful for Zope 2.7.X as it still
uses ZODB 3.2.  Zope 2.8, which is supposed to ship with some version of
ZODB 3.3, is still a long way off too, AFAICT.  Darn.  Do you have any
recommendations for how to implement this in ZODB 3.2?

Yup, that's not a problem, assuming we have the machinery to register a
new transaction manager.
