That would be useful even for local servers using TCP sockets, but
server-running-p currently does work only for local sockets.
The following is a simple way to at least know whether there's a
process called Emacs with the same pid that is stored in the
authentication file.
(with-temp-buffer
(insert-file-contents-literally (expand-file-name server-name
server-auth-dir))
(skip-chars-forward "0-9:.")
(let ((case-fold-search t)
(proc (assq 'comm (system-process-attributes (read (point-marker))))))
(and proc
(string-match-p "emacs" (cdr proc)))))
