Very cool!

I had heard there was really good work to fix the GIL, but that Guido 
insisted that any fix have zero-performance hit on single threaded code. 
Or something like that. A separate binary might have been the way out of 
that impasse.

I can imagine packages being "clever" in ways that can't handle 
multithreading.

Still, very good news for Python programmers. (And would be for me, were 
I still a Python fan.)
