If it needs to be done per sleep event. On the other hand, if you can
set a per-thread flag or tunable which says 'you can always delay my
wake by up to N milliseconds', then you don't need special magic in
poll/select/nanosleep/etc for that. And it would make it easier to
modify userspace to use it too. In fact, you could even use it with
binary-only unmodified userspace, by executing a program with the flag
already set.
