Ok, the reason for the confusion is that pthread_wait_np() does work to
some degree even if the thread is not periodic. Yes i failed to RTFM.
the thing that i don't like about the doco on pthread_suspend_np() is
that it says the thread may not block right away, which causes me some
FUD.
Another problem has occurred to me. Is it ok to pthread_kill(wakeup) a
thread that isn't suspended?
