I've never reported this as a Python bug If you do, I'll probably add a comment like the above ;-)

because I've considered the antivirus SW likely to be the culprit. Could be. FWIW, Norton AV was running during the above.

I see a similar phenomenon (sp?) on XP SP2: test_mailbox fails to me, with permission denied in some (random) test. I believe this is due to Tortoise SVN: test_mailbox creates a few directories, then Tortoise detects them (thanks to file change notifications) and tries to walk them, to find out whether that directory is under subversion control.

Before Tortoise is done, test_mailbox tries to delete the directories. This (somewhat?) fails - there apparently is a "delete pending" state somehow in the system (sysinternals filemon sometimes shows DELETE PEND as the result of a call). Then, the next test will fail with permission denied.

This is a heisenbug: different runs will fail in different tests, and letting sysinternals perform complete tracing make the failure go away.
