Ugh, well, if I were going to do that kind of thing (and I admit that
I like the cleanup LIFO stack idea a lot), I would have some utility
self.db = self.setupScratchDb()
self.tmp = self.setupTempIO()
# save the manual self.cleanUp.append() calls for those cases where
they really are one-offs.
I've also done things in other non-test code where the creating
function returns a tuple:
new_thing, clean_up_thunk =
Because, really, it is an encapsulation failure if the code asking for
a new "thing" has to know how to clean it up.
