I understand how to launch the server and how to launch from CLI. May be
that I was not clear enough.

I just want to know how to cleanup (gracefully) the residual process
when there are no more clients connecting. i.e. case (2) above. User has
started Emacs by clicking on the "Emacs (Client)" icon in a graphical
environment.
