The specifics are that it keeps on switching between handling one
message from the todo queue and spawning one local/remote delivery,
which, somehow, seems to be fatal for performance.
I don't know if it sucks more than sendmail. Sendmail doesn't have a
todo queue, and it often has several processes spawning at once, because
of it's nature.
