[Python-Dev] test_doctest failing, but perhaps by accident

Last time we had something like this it was a specific dependency
between two test modules, where if test_A was imported before test_B,
things were fine, but in the other order one of them would fail.

I noticed that someone (Jeremy?) checked in a whole slew of changes to
test modules, including test_support.  I also noticed that stuff was
added to test_support that would show up if you did "from test_support
import *".  I believe previously this was intended to only export a
small number of things; now it exports more, e.g. unittest, os, and
sys.  But that doesn't look like it would make much of a difference.
