How were the processes spawned: directly by the job script, through some
TM-aware program (e.g. pbsdsh, OSC mpiexec, OpenMPI mpiexec), or using
an intermediary such as rsh or ssh?  If it's the latter, TORQUE's
pbs_mom has no knowledge of their existence and thus cannot deliver
signals to them.  OTOH, signal delivery to jobs and their associated
processes does work in my experience, so long as all the processes are
children of either the job script or pbs_mom.
