That's exactly correct.  I keep node 0 (cpus 0-1 and mem 0) free since we have had trouble in the past if the I/O is restricted in any way.  There is the additional benefit that /batch and /boot are siblings rather than parent-child.  All general purpose work runs in /boot, including a limited amount of testing.  Production runs (which may last for several weeks with multiple processors) go into /batch.
