Which reminds me of a nice exercise that I discovered with a colleage:
ZODB currently supports two (old/new) styles of the two-phase-commit for
backwards-compatibility.

The whole code is much harder to understand because of the support of
the two versions of the TPC protocol. 

Just FYI and maybe someone thinks it might be a good idea to clean up
too. My current todo list is way too long, but I'd put it in the
collector if it's a worthwhile thing.
