qmail-smtpd from inetd or standalone?

[Antonio Messina]

I have a little question: i was thinking that running a program from
inetd introduces an overhead; on a high traffic smtp server this
implies many many forks. Is there a way to setup qmail-smtpd to run
standalone, as we can do with apache, that when it starts already has
a number (5, 10, or some other configurable number) of child listening?
If that is possible, is a good solution? and how could it run with
tcpd or tcpserver?

Thanks,
Antonio Messina.
