 Since there's no traceback, I don't think we can reliably conclude that
 this is the same bug. {{{test_filesystem}}} is a '''huge''' test, and
 there could easily be more than one nondeterministic bug in it. Let's keep
 this ticket for the check that we know fails at
 [source:src/allmydata/test/test_system.py?rev=5051#L1101].
