It sounds that way!  Would it be sufficient then to just require that the
process abortions start at the leaves of the tree and work their way back to
the root, waiting for the children to go away before starting on the parents?
I know that it would be slower than the current method, but the gain of not
having orphan processes would, I think, be worth it.  MPE could report partial
abort or some such.  The job/session would be left in an ugly state, but, I
think, not quite so ugly as it is now.
