Therefore, I'm in favor of having it on by default. If certain use cases
make it problematic (e.g. Apache creating directories which you then
cannot delete), there should be a way to turn it *off*. Perhaps the
existing machinery to turn of byte code generation at all might be
sufficient.

As for the original question (funny umasks), I think my proposal is
"tough luck". Don't try to be super-smart; as Antoine explains, it gets
worse, not better. If the user has arranged that Python will create
unusable directories, the user better changes his setup.
