It's not an ugly hack, it's a well known feature. Add you don't have to
change a lot of places, too. It's sufficient to add the alias at the
entry point of your application (the script that starts your app). Once
the alias sys.modules]'mmap'] = ralfmmap is set, every import mmap gets
your ralfmmap.
