Based upon my reading of the renice(8) man page, the above would seem to be the correct behavior. From the man page: ... fiats.) The super-user may alter the priority of any process and set the priority to any value in the range PRIO_MIN (-20) to PRIO_MAX. Useful priorities are: 20 (the affected processes will run only when nothing else in the system wants to), 0 (the ``base'' scheduling priority), any- thing negative (to make things go very fast). This sounds to me like a priority 20 process shouldn't get any CPU unless no other processes want CPU cycles. Am I misreading something?
