Please calm down. You apparantly already get worked up about one of the
secondary problems. I didn't say 'sleeper starvation' or 'rounding
error', these are your words and it's your perception of what I said.
sched_clock() can have a low resolution, which can be a problem for the
scheduler. This is all this program demonstrates. If and how this problem
should be solved is a completely different issue, about which I haven't
said anything yet and since it's not that important right now I'll leave
it at that for now.
