It's the right thing to do if you're already within a few percent of
your maximum network capacity.

That isn't the situation for AOL. (Some of you may be amused to note
that AOL does about two _hundred_ retries of a message in its first day
in the queue.) It isn't the situation for me, and I'd be surprised if
it's the situation for any of you.

I don't mean to say that bandwidth is irrelevant---but, just as in any
other kind of programming, you should _profile_ and spend your time
worrying about where most of the bandwidth goes.
