I'm wondering whether something could be gained by
cacheing the results of sys.path lookups somehow
between interpreter invocations.

Most of the time the contents of the directories
on one's PYTHONPATH don't change, so doing all this
statting and directory reading every time an
interpreter starts up seems rather suboptimal.
