[issue7946] Convoy effect with I/O bound threads and New GIL

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

We could try not to release the GIL when socket methods are called on a non-blocking socket.

Regardless, I've re-run the tests under the Linux machine, with two spinning threads:

* python 2.7: 
25.580 seconds (409914.612 bytes/sec)
* python 3.2:
32.216 seconds (325485.029 bytes/sec)

(and as someone mentioned, the "priority requests" mechanism which was in the original new GIL patch might improve things. It's not an ideal time for me to test, right now :-))
