Why do you want to overwrite the existing module instead of using a different name like ralfmmap?

import ralfmmap as mmap sys.modules]'mmap'] = mmap I thought about that (ugly hack) too. I would have to change the imports at a lot of places (and revert the changes when we switch to python 2.6). (whereas on Unix I would only have to do install the new mmap module).

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.
