Chuck, thank you very much for the info.

Can I trouble you a little bit? Is there something
equivalent to rtprio(1) (/usr/sbin/rtprio) in Mac OSX?
If there is, could you also send following:

1. rtprio <PID of /usr/sbin/coreaudiod>

2. rtprio <PID of windowserver>

3. rtprio <PID of iTunes>

4. rtprio <PID of xterm>
