[issue9600] multiprocessing Pool instantiation crashes on 64 bit 2.6.6rc1 under Windows 7

Martin v. Löwis added the comment: Notice that this is also a duplicate of #9144, which was fixed for 2.7, but nobody bothered to move the fix to the other branches. This goes all back to #7902, which has now introduced an incompatible change into 2.6 (otherwise, changing multiprocessing shou

Barry A. Warsaw added the comment: Please upload a patch specifically for 2.6.6 finally so that I can review it (and test it locally). It *seems* safe enough so if you and I both have a high confidence it won't regress anything, and it can go in before Monday, then I might approve it. I sti

Brian Curtin added the comment: Ok, it turns out this is in fact a regression from 2.6.5. My prior investigation for that 3.x issue must not have been on the 2.6 version I thought it was. Barry: the fix from #9513 (e.g., r83722) will correct this. -- priority: normal -> release block

Brian Curtin added the comment: I should correct myself. As seen on the 2.6 Win7 buildbot[0], test_multiprocessing is skipped there likely due to the "from ._multiprocessing..." ImportError. I kind of remember this now but didn't want to backport the fix to release26-maint since it was frozen

Brian Curtin added the comment: I just fixed a similar problem for #9513 but the problem was only ever seen when test_multiprocessing was run through regrtest on 3.x on Windows. Removing the relative import dot on _multiprocessing imports let them succeed. I've never actually seen this cause
