Summary: one more statement about RUN

Sorry about being late with this comment, but I was unable to post news
for a while.

The problem is actually due  to the AMIGA  scheduler.  It is not a true
round robbin with  pre-emption.  Without  pre-emption, a process with a
lower priority  may  never  run given  the  presence of a compute bound 
process with a higher priority.

The RUN command should  not, however,  change a processes priority. The
analogy with csh  reducing the  priority  of  background tasks is not a
valid one. The AMIGA paradigm is  that  of multiple concurrent sessions
not one session with some jobs running in the background.
