By design, most Postfix daemon processes terminate voluntarily after
$max-use (default: 100) client connections, or after $max_idle
(default: 100) seconds of inactivity.
One a busy system this gives most of the benefits of preforking,
without the dangers of memory leaks in libraries. On an idle
system no-one cares about performance.
