At this point, would you advise me to add even more to the existing hodge podge, or to create a third sibling test support module?  My patch adds closely related test support functionality.

Incidentally, this discussion relates to the point I was getting at in the python-dev thread in the past couple days about how restrictions on refactoring test support code for maintenance releases can affect the quality of our test code.  I am still struggling with how to approach that.
