That's interesting, thanks for directing me to it.
The TransactionAgent code seems very fragile and is a perfect example of
why we need some hooks in ZODB. For example, it assumes that
Connection.sync() calls the public abort method to end a transaction
rather than making some internal call, and therefore is relying on
implementation details of ZODB.
Adding hooks to support things like TransactionAgent was discussed at
one point [1], but it appears that nothing became of it.
