Problem is, most modules don't own their python bindings.  So:

1) Your need to have python bindings installed before you can test the
module.  Circular dependency BTW.

2) Your tests may hit binding bugs.  It's hard to know.

3) Dependencies.  No dependencies is part of the design Tim brought.

If it's like 2000 lines of code and 10 entry points, the overhead is
