I don't know if the current code does, but it certainly good.
Some versions of inetd will listen for RPC services (like ypbind or ypserv) and start the daemon only on demand.
It might be a bit tricky if portmap (or rpcbind) were started on demand. You would want to be able to feed it a list of programs/binding to be able to report immediately rather than waiting for them to be registered.

I have already patched rpcbind to be socket-activated. It is then started as soon as some client wants to query or register a service; or alternatively at startup but parallelized.
