Yes, and that handling works for me. The problem is that a stop;start
fails when the stop takes a bit, whereas a stop-with-restart will always
be just fine.
What happens now when I do a cluster restart is that some of my Mongrels
end up just dead, as they actually stop (gracefully) after the start has
already been called for. I could resolve this using a forced stop, but
I'm looking for a more, not less, graceful process.

Ah, so I understand why you made the change to have a cluster restart do
a stop;start. We don't change the cluster configuration, so we aren't
hit by that problem.
But would it be possible to get an alternative command added that does
do an actual restart? If not, no worries, I'll hack it in on my end.
