Sorry for the multiple postings, but I think I have it right this time...
This is kind of bizarre, but what can you expect from Unix?
Under true BSD 4.3, PRIO_MAX is defined as 20 and PRIO_MIN is defined
as -20. Regular users can "nice" their processes from 0 to 20.
Under two BSD 4.2 workalikes (DYNIX and Ultrix) that we have here,
PRIO_MAX is defined as -20 and PRIO_MIN is defined as 20 (i.e. backwards
from BSD 4.3 and thus the reason for my confusion). Regular
users can "nice" their processes from 0 to 19 (despite the fact
that in the Ultrix man page for "nice" it says from 0 to 20).
