Subject: [svn-r3663] Purpose:     Improvement Description:     Changed the
 default value of $NPROCS from 2 to 3.  This is the     value libSAF uses
 since 3 processes have a much bigger chance     catching parallel errors than
 just 2 processes. Platforms tested:     Modi4 (IRIX64) both serial and
 parallel modes.
