[Python-Dev] PEP 3147, __pycache__ directories and umask

I don't think an ImportWarning should be raised: AFAICT, we are not
raising one, either, when the pyc file cannot be created (and it may
well be the case that you don't have write permission at all, which
would trigger lots of ImportWarnings).
