*None* of our FS tests are running while this problem persists (and
they're not alone). That's not the sort of thing we can wait on...
Maybe we have some gratuitous non-use of the testing kernel we can
remove (I'm not sure), but that's the sort of thing that needs to be
discussed across teams so we can deal with it proactively instead of
just finding out when the nightlies start failing.
