Does this will work reliably on Windows, where path separators can be / or \, and these are largely equivalent? Should we normalize separators on Windows, or can we assume everything is normalized here? I noticed that you added a call to os.path.normcase, so maybe this is already ok.
Maybe update docstring to mention Windows-specific issues, and case insensitivity issues?

Documented the shortcomings of the faster function + invariants we require in modulefinder. Also renamed the function so it sounds a little scarier
