Hrm.. True, it isn't a real-time timer. I forgot about that. It
decrements both when you are in user and in kernel space though. I guess
a sleep() call is neither.
That does explain it nicely. What we really need are multiple real-time
timers. We can't use ITIMER_REAL because SIGALRM is used by Apache.
