Besdies what has been said in another thread (regarding 1.4 and
checkpointing to shared directories), you might want to make sure your
app is terminated if you send a SIGTERM to it. Some apps might ignore
SIGTERM or handle it in a way that does not cause the apps to quit.
ompi-checkpoint --term is simply ompi-checkpoint + sending SIGTERM to
the application (not sure whether SIGTERM is sent to each process
individually or not).
