Subject: Re: [OMPI devel] Orte cleanup

I believe I have at least helped reduce this with r17761. I added the
ability for procs to detect that their "lifeline" connection (either the HNP
for unity routed, or their local daemon for tree) has been lost and
gracefully abort.

Let me know if that helps
