pbsdsh spawns processes through the TM API, which only works in the job
itself and not prologue or epilogue.

If you're trying to run something on all the nodes assigned to a job,
you should probably do that in {pro,epi}logue.parallel, although keep in
mind that you'll need to run the same commands in {pro,epi}logue for
them to be executed on the mother superior node.
