Also, won't foo.py be wasting time in most cases by
defining python versions that get overwritten?

Instead of defining things directly in foo.py, maybe it
should do

   try:
     from cFoo import *
   except ImportError:
     from pyFoo import *

Then the fast path will be taken if cFoo is available,
and you can directly import cFoo or pyFoo if you want.
