[torqueusers] Signalling on multi node jobs.

On the mpiexec list we have been discussing how to get suspend/resume work 
with mpiexec.  I thought that if you send a signal using qsig or whatever it 
gets forwarded to all nodes in a job, but that does not seem to be the case.  
Only the mother superior receives the signal, is this the intended behaviour?

This has implications on how mpiexec is supposed to handle signals.  If the 
above behaviour is the right one then it must forward the signals.  If not, 
then it can ignore them as they will be sent to all nodes anyway.
