Improve interrupt safety.

Transitions are made interrupt safe by making a successful transition come down
to a single point; iff that point is passed, the transition is complete,
otherwise the step must be performed again. It is up to the user to identify
when a message needs to be processed again(Perhaps some assistance here may
be in order).

Additionally, change the Transaction's API to used regular named methods. After
some -m timeit sessions, named methods appear to be fetched and executed faster
than __call__/__lshift__/etc. (I imagine Python optimizes the common case.)
