/** Program to test AIX priority values
 *
 * This program will schedule itself on the SCHED_RR scheduler and set it's
 * priority to 42.  Then it will print it's pid and do nothing for 10 minutes.
 * You can finish it earlier by sending a SIGTERM.
 
 * Since it changes the scheduler it will have to run as root and it will only
 * run on AIX due to the AIX specific setpri() system call. */
