Process priorities

Hi,

I've noticed if I run 2 CPU-bound processes (for testing, 2 copies of
seti@home), leave one at the normal priority and nice 20 the other, the
nice'd process still consumes about 40% of CPU (this is with 'ps l' -- 'top'
shows about 20%). I thought that setting nice 20 would mean the process
would run only when nothing else was running -- is that right?

Cheers,
;) jimmy.
