I susppect you may e thinking there is only one,
long-lived, delivery process - which does all deliveries.

That isn't so. A process is started when a delivery is
needed. It does what it can, which might handle more
than one message, and then terminates. There could be
multiple delivery processes running in parallel, and there
could be none at all, at any given moment.
