It is on purpose. Note the following fragment from server.el:

I see.
In my .emacs, I change `server-name' to be process-specific, and
create a symlink to the generic name:

(setq server-name (format server%d (emacs-pid)))
(let ((x (format emacsclient -s %s server-name)))
(setenv VISUAL x)
(setenv EDITOR x))
(server-start)

(when (= emacs-major-version 22)
(make-symbolic-link
server-name
(concat server-socket-dir /server)
t))
Is this a sensible approach to adopt as default in CVS Emacs, or would
it have problems for e.g. DOS users (who have no symbolic links)?
If this approach was adopted, `server-sentinel' could happily remove
it's socket file, leaving a broken symlink instead of a defunct
socket.
