A friend of mine's got a setup where he wrote a wrapper or something for mpg123 where he sets it's priority to something ridiculous. Higher than 'nice' will set it, I think he said it preempts the kernel in some places. ;) Needless to say, this makes the box useless for anything else while playing mp3s. :) His is a plain old Pentium laptop, not sure if it was that slow even (50MHz). Yeah. So you can look into scheduling system calls, sounds fun. :) HTH, Mike McGuire
