I suppose I was thinking about the stale .pyc file problem, mostly.

zc.buildout/setuptools/distutils (I'm not sure which part of the stack
is to blame) likes to compile modules in a temporary directory and then
move the .py and .pyc files to their final location.  As a result,
__file__ points to the now-nonexistent directory.

Aside: I never understood the reason for storing the value of __file__
in the .pyc/.pyo file itself.  Why not set it to the correct value on
import time?
