I've unset all the resources_*.nodes settings for the queue and gotten
maui/torque to actually read the ncpus= value from the PBS script file
since this is actually what sets the PROC limit. According to the
source src/moab/MJob.c line 11483, ncpus is tied to the PROC limit.
Also the comment in src/moab/MPBSI.c on line 1676 validates this.
However, for some reason ncpus was not being read previously from the
pbs script file even when all references to resources_*.ncpus were
unset in qmgr.

Now that I know how to get the PROC resource limit to change, I'll
play around with the qmgr settings again to try to set limits before a
user even submits a job. Then I'll test to see if these limits are
enforced for MPI programs (across nodes).
