Some other questions whose answers may be worth including in the man page:

* When was SCHED_IDLE added?  (Actually, who added it?)

* Why was it added?  (What are the particular benefits of the new
sceuling class as opposed to using a very low nice value for
SCHED_OTHER?)

* What's the difference between SCHED_IDLE and SCHED_BATCH?

Cheers,

Michael
