Geordie,

  that is exactly what I was looking for.

  A question on a sidebar ... How did you learn that? I had a good look at the 
renice command man page and after I read your mail once again, but didn't 
find anything.

  Actually I tried it out and it didn't work for me. What I tried is:

rock:~# renice -10 pppoe
0: old priority 0, new priority -10
rock:~# renice -10 /usr/sbin/pppoe
0: old priority 0, new priority -10
  
  And top also show a nice value of 0.

  Any ideas?
Cheers,
Mariano
