Fyi, here is the output using the unmodified Windows GIL, i.e. without my patch being active:

== CPython 2.7a4+.0 (trunk) ==
== AMD64 Windows on 'Intel64 Family 6 Model 23 Stepping 6, GenuineIntel' ==

You see results virtually identical to the ROUNDROBIN_GIL implementation. This is just do demonstrate that Windows has had the ROUNDROBIN_GIL behaviour all along. |
