1. Was specifically involved with work on this subject on Irix and True
Unix (Digital Unix on Alpha) -- no such thing like decaying nice on
these systems.

2. There are  Irix specifically tools like npri or schedctl (from within
a process)- but they need to be specifically activated by root.
In Linux (and Irix) sched_setscheduler can be used to affect the
policy-- but still only specificaly activated by root or a process with
uid equal
to the uid of the process affected.
