pick up schedtool, and these are the choices it gives:

    -N                    for SCHED_NORMAL
    -F -p PRIO            for SCHED_FIFO       only as root
    -R -p PRIO            for SCHED_RR         only as root
    -B                    for SCHED_BATCH
    -I -p PRIO            for SCHED_ISO
    -D                    for SCHED_IDLEPRIO

then for example to start up something as SCHED_IDLE:

  schedtool -D -e ./somecommand.sh
