I haven't looked at the new code, but presumable the CRI peeps are making
pbs_mom report to the new server.
It is an active/standby arrangement. The "active" server works as normal. The
"standby" server idles until the active server dies and clients and MOMs should
start talking to it.
Again, I'm presuming it because I haven't actually looked at the new code.
