there are a few applications out there that seem to believe that you
can improve audio performance (i.e. less dropouts under load) by
changing their own nice value. this represents a complete
misunderstanding of the differences between conventional Unix
scheduling ("SCHED_OTHER") and realtime scheduling like SCHED_FIFO and
SCHED_RR. using nice can, under a few circumstances, make a
difference, but its use basically means that the developer(s) really
don't understand what the issues are.

presumably some distros believe that their version of limits.conf
should accomadate this kind of misconception. i don't think that
limits.conf should be specifying a nice value, at least not in
connection with audio/music applications that inherently need realtime
scheduling.
