This seems to be used only in the tests, I guess it would be useful if you were using multiple transaction managers in a single thread. Can you think fo examples where that would happen?

Perhaps if you wanted to use an event based (as opposed to threaded) server.

Yes, annoyingly that's exactly what I'm doing ;-) I need to manage transactions in a twisted application, so I guess I can't just do: import transaction transaction.get() :-( I don't suppose anyone has examples of using the transaction package in an asyncronous, event-based environment? cheers, Chris
