Yeah I guess so - it would only matter if they add work in one
of the callbacks we use to remove keys, interfaces, etc. This
might be a good case for the in_suspend flag. Or, we could just
flush the workqueue again at the end of suspend to make sure
nothing was added.
The other thing I don't get is why STR works fine but STD hangs,
from my reading of stuff in kernel/power they should be the same
with respect to order of task-freeze and suspend.
