The only problem I could see is the socket. The pre-forked() back-end would
have to do the accept() for the new connection, but you could always have a
forked process waiting to go in the accept() routine. When it accepts a new
socket, it sends a signal off to the parent back-end to fork() over (couldn't
resist) a new backend.

That way there would be no fork() over head for new connections.
