I'm using this:
(when (and (file-exists-p (expand-file-name server-name server-socket-dir))
(let ((status (call-process "/usr/bin/lsof"
nil nil nil
(expand-file-name server-name
server-socket-dir))))
(or (not (numberp status)) (equal status 0))))
(setq server-name (format "%s-%d" server-name (emacs-pid)))
(add-hook 'kill-emacs-hook
(lambda () (condition-case nil
(delete-file (expand-file-name server-name
server-socket-dir))
(error nil)))))
(server-start)

Kinda chicken-and-egg: how do you contact the running Emacs without the
server?
Andreas.
