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.
