I've made a great effort to avoid needing to use weakref elsewhere.
Can we promote the after function to module scope like opener and
thereby avoid this problem case too?

If we must use weakref, I'd prefer to find a way such that it was
invisible to users of the transaction class, like using a wrapper.
