The logic you suggest for detecting .pyc files seems similar, but I
haven't determined if it's identical, to the logic in

 zope/testing/testrunner.py

in the "zope.testing" module.  Is it wise for every module that needs to
detect and eliminate "stale bytecode", as zope.testing so whimsically
puts it, to have separate logic that needs to be maintained separately?
Could the logic that you have suggested, Chris, and the logic in the
zope.testing module, be somehow refactored into a little common toolkit
so that martian and other Zope packages will all handle stale bytecode
in the same way?

Because we all know how much Grok needs another dependency. :-) Is there
maybe a Zope module we're already using where this logic "really
belongs"?
