Dunno 'bout fast file systems, but I agree it sure would be nice (pun intended)
if a non-setuid process had a way to modulate its priority (both upward and
downward) within the constraint of what it was granted at invocation.
(Setuid root processes can nice() themselves up and down at will, but I presume
the emphasis is on user code?  Or maybe it is acceptable to be setuid root
in a dedicated applications environment [not a general purpose user environ-
ment]?)
