Ok, the first idea was a bad idea. Will try the second, or the
alternative proposed by Philippe.

What I dislike most, is the lack of return values check. This may work

shutdown using pthread_cancel, after all sigwait and *nanosleep are
cancellation points, so it should work even without resorting to cleanup
