I don't know if this has been mentioned before or not, but I'll bring it up
now: massively concurrent networking code on Windows. Socket connections could
be passed off from the main interpreter to sub-interpreters for concurrent
processing that simply isn't possible with the global GIL (provided the GIL
actually becomes per-interpreter). On *nix you can fork, this would give
CPython on Windows similar capabilities.
