Thanks a lot for this test, since it actually gives me a hint of what
the problems Darren was seeing with GUIs may be...

No, that's because I monkeypatch doctest, and the reload() undoes the
monkeypatch.

Yup, that global in doctest is just a bad idea, since the entire
module is stateful.  Stupid design on their part...

I'll also try to address this, but the problem you uncovered earlier
is MUCH more serious.

Thanks again for giving me such a small, clear test, it will make things easier.
