> Too bad, test_resize() failed again while testing commit 56e162ad5c5d3effe9b4f05d0179e1b6a2a2d9b8 :-( So this fix was not enough.

I am not sure anymore about this statement. I had a bug in my watchdog code, that I fixed after this failure.

I ran again the test during 3 hours and it didn't fail.

I reverted all my local changes, I rebuild Python 2.7 in debug mode to get a fresh python_d.exe, I removed all __pycache__, and then I ran again the test during 1 hour: no fail. I ran 4 instances of the test in parallel during 1 hour: no fail.

Hum, it *seems* like the bug was fixed.

Since it's a race condition, it's not possible to say that it's really fixed. But my test results show that the bug is very likely to be fixed, so I close the bug.

I will watch AMD64 Windows8.1 Refleaks 2.7 buildbot slave next days to check if the bug occurs again.
