SubjectProcess priority in 2.4.18 (RedHat 7.3)
Just installed RedHat 7.3 with kernel 2.4.18 and noticed that my network 
no longer functions when my CPU usage is at 100%. Looking at the
priorities of the application that I was running showed a priority of 35
(thats what `nice ./test` produces). Then looking at the priorities of
all the other processes shows a range from 15 to 35.

All the main kernel processes run at 15 except ksoftirqd_CPU0 and
ksoftirqd_CPU1 which run at 35.

None of the documentation on my system (`man nice` etc...) mentions
anything about priority levels between 15 and 35, they all say -20 to +20
(as it used to be).

So, why the change the priority levels? And why my test app (at any
priority level) starves out my network?

I am running an SMP box.

Thanks.
