I believe all it takes is that pbs_mom not trying to be smart about ex-
children, and not communicating with the batch server about them. The
server is designed to handle the situation.

Yes, and I think diverting the discussion of "pbs_mon -p" to whether
to start pbs_mom at boot time downplays the importance of this new
annoying default behavior issue. I'd like it better if the subject
line had changed to something else for that discussion.

We are running 2.4.1b, I don't know about other versions. We got it
from Cray, so we'll open a Bug with Cray.
