 This program sets or gets the io scheduling class and priority for a program.

 As of this writing, a process can be in one of three scheduling classes:
-
 .IP "\fBIdle\fP"
 A program running with idle io priority will only get disk time when no other
 program has asked for disk io for a defined grace period. The impact of idle
 io processes on normal system activity should be zero. This scheduling
 class does not take a priority argument. Presently, this scheduling class
 is permitted for an ordinary user (since kernel 2.6.25).

 This is the effective scheduling class for any process that has not asked for
 a specific io priority.
