Comment (by dustin):

 Returning to the topic of the bug, I totally agree that additional testing
 would be great.  I'm not sure how best to test the interaction with virus
 checkers, for example.  We've also had a hell of a time getting donated
 Windows systems to stay up and functional, so we don't currently have any
 windows coverage.

 Regarding the patch, I like the form -- there's really no point in
 retrying individual files, rather than retrying the whole remove a few
 times.

 There's still the issue of using time.sleep, though -- that will cause the
 entire buildslave process to stop, which means any other commands that are
 in progress at the time will freeze.  It'd be better to use
 `reactor.callLater`, which in turn requires `rmdirRecursive` to return a
 `Deferred`.
