That's not correct in this case, because the sound servicing routine is
realtime, which makes it special.  Furthermore, Zinf is already trying to
provide the kernel with the hint it needs via PThreads SetPriority but
because Linux has brain damage - both in the kernel and user space imho - the
hint isn't accomplishing what it's supposed to.

As I said earlier: trying to detect automagically which threads are realtime
and which aren't is stupid.  Such policy decisions don't belong in the
kernel.

Having hacked a little bit with vsound I can say that many sound players
do not use at 100% the buffering the sound card/kernel is able to provide
and they still use 4-8Kb feeding chunks. That require very short timings
to not lose the time.
