...unless you use Linux 2.2 + the lowlatency patch, and sets the mp3
player thead to SCHED_FIFO. That makes the player run as a true hard
real time task, ie it will never drop-out, and it'll just take the
CPU time it needs. (Provided your CPU is fast enough, obviously! :-)
In case you have missed it, see
http://matrix.crosswinds.net/~linuxmusic/lowlatency.html
It seems like a refined version of the lowlatency patch is going into
the mainstream 2.4 kernels... (Cutting scheduling latencies does
bring advantages in other areas than real time processing as well.)
