I would like to renew the discussion now that "there is a PEP" to see if there are any outstanding things people would like to get resolved. I chose to continue to push it for 2.6 / 3.0 inclusion due to feedback both here and elsewhere that people would rather see this in sooner in some form, rather than later (i.e.: 2.7/3.1).
+1 from me (under the 'multiprocessing' name, with the understanding that some code duplication with other parts of the standard library may still remain in 2.6/3.0).
+1 from me as well, and I support the rename to multiprocessing ("processing" is just too much of a common word).
This will provide a good short-term answer to those who still clamor for dropping the GIL.
I'm very happy this is going forward. It's a big win.
