As I stated above, we're already doing the "standard thing" (with rsh).
What I want to do is be able to do something like "exim -q2m" and have exim
quickly try connectivity to all the downed sites. That way, if someone is
connected, they get their mail.

The only problem I forsee is the freeze-time being too long.
