Read my message last night about torturing majordomo.

Why should it? It sits between two sendmail invocations. Sendmail won't
even deliver the mail (i.e. invoke wrapper in the first place) if the load
is too high. It won't even accept new connections if the load is really
high. If your system cannot handle the loads that it's configured at, then
reduce them.

We've been over this several times. I've stated the direction I think 2.x
should take, which involves constantly running daemons that keep the
necessary state to minimize startup time.
