   You can also use renice, to change the process priority of an already 
running process.  Unfortunatelly, you can only lower the priority of the 
process.  With renice, You need to be root to put higher the priority of 
a running process.  Still, it is usefull if you want to lower the 
priority of a group of process that take lots of ressources on a system 
(ex. lowering the priority of a big "find" request all over your hardisk 
while you are doing something else more important).

   As far as I know, both nice and renice are available for every modern 
Unix systems.
