Hi,
I have found that if I run Audacity (sound editor ports/audio/audacity) and do 
a CPU intensive task (eg noise removal, FFT filter, etc) my system becomes 
almost unusable (takes seconds for the mouse to respond, X shows signs of 
getting CPU very very rarely etc).

I attempted to fudge a fix by reniceing X -20 and Audacity +10 but it didn't 
seem to make things any better.. I also found that in top the NICE column 
bears little resemblance to my setting.. I saw values like -100, -140, and 0.

I haven't tried the same thing in SCHED_4BSD.. My kernel dates from around the 
beginning of February (-current)
