How do I do that?

Since the data manager I'm working on is for a transcation message 
sending implementation, maybe it should be an after commit thing too?

My other thought was to have it commit the message send in tpc_vote, and 
make sure it sorts before zope.sqlalchemy. That way, if the message send 
fails, the "transaction" will be aborted, and that will include rolling 
back the zope.sqlalchemy session rather than committing it.

Views?

cheers,
