I think this is off-topic..
Anyhow, the priority values for the processes range from PRIO_MIN (-20)
to PRIO_MAX (20). Zero is neutral. This is how the scheudling of the
processes are arranged. A negative value like -15 means the process
will go faster than if the priority value was 15.
So if you have a dedicated SETI@Home computer, you could run 'setiathome'
with a priority of -18 for example:-)
