I didn't spot any replies to the actual question ;).
Short answer: I don't know. The setup/teardown part of doctests
is, IMO, quite annoying. There was some mention a few months back on
this list of using reST-style footnotes to specify setup and teardown
code (related to Zope, I believe). That would be a good solution to
Right now I would approach your problem by developing a utils module
that contains functions to do the setup/teardown, and then I'd call
them explicitly in the doctests.
