[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

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) ... ERROR
test_nullpat (test.test_bufio.PyBufferSizeTest) ... ok
test_primepat (test.test_bufio.PyBufferSizeTest) ... ok

======================================================================
ERROR: test_primepat (test.test_bufio.CBufferSizeTest)

Is there some kind of anti-virus installed on the machine?
