[concurrency] Reworking the GIL

[Antoine Pitrou]

Hello,

I've just noticed that this list exists (not that it seems very active).
So I thought I'd send you a link to the recent work I've done to improve
the behaviour of the GIL, the results of which you can find in the SVN
sandbox :

(it also gives a name to the "Dave Beazley effect" ;P)

Regards

Antoine.
