test_bufio fails sporadically on the AMD64 Windows7 SP1 buildbot, e.g.: http://buildbot.python.org/all/builders/AMD64%20Windows7%20SP1%203.x/builds/161/steps/test/logs/stdio test_nullpat (test.test_bufio.CBufferSizeTest) ... ok test_primepat (test.test_bufio.CBufferSizeTest) ...

Looks similar to the sporadic test_reprlib failure. Roumen has explained that here: http://bugs.python.org/issue14599#msg162727 I didn't test myself though, just a guess.

I've changed the malware scanner to disable real-time protection and have disabled scanning of the buildbot directories. Note that I could reproduce intermittent failures when using '-j' of regrtest, but with these changes they no longer appear.

The implementation of test.support.unlink() was changed since. It tries to change permissions of read-only files, and repeat attempts several times. It looks more reliable now. Is this issue still reproducible?

I've not seen this issue on that worker for a very long time; closing the issue.
