I was always wondering why one can set process priorities under Linux
only in the range 0..14 (for non-root users). Other *IX'es seem to
allow more "fine-grained" settings in the range 0..20 (or 0..19).
(At least this is what they make their users believe...).
Looking at linux/kernel/sched.c (Kernels 1.2.13 & 1.3.25), I discovered
that the range of settable values is also hard-coded (i.e. not derived
from any header file). Can anybody enlighten me why this is so?

It takes all your running you can do to keep in the same place.
If you want to get somewhere else, you must run at least twice as fast as that.
