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.
