And this is what might make evaluating importlib tough; while the performance is 25% of what it is for import.c, being able to import over 300,000 times/second is still damn fast.
Yes, that's very encouraging. I guess the final test would be to take something like Mercurial, and time e.g. "hg version" both with the builtin-import, and with importlib enabled as default import mechanism.

Antoine.
