Might make more sense to put this a bit earlier, to avoid the
awkward lock juggle. In theory it shouldn't make a difference
if we do it _before_ doing new work, or _after_ doing work. We
should only be rescheduling if it's running for quite a while.
How about putting it after the flushing of signals instead?
