How about the attached patch?  It enables us to register Apple event
handlers at the Lisp level as follows: (the code is included in the
patch)

  (put 'internet-event 'mac-apple-event-class "GURL")
  (put 'get-url        'mac-apple-event-id    "GURL")

  (defun mac-ae-get-url (event)
    (interactive "e")
    (let* ((ae (mac-event-ae event))
	   (parsed-url (url-generic-parse-url (mac-ae-text ae))))
      (if (string= (url-type parsed-url) "mailto")
	  (url-mailto parsed-url)
        (error "Unsupported URL scheme: %s" (url-type parsed-url)))))

  (define-key mac-apple-event-map [internet-event get-url] 'mac-ae-get-url)

Then Emacs can receive kAEInternetEventClass/kAEGetURL Apple events as
in the following form, and it is handled by the command
`mac-ae-get-url' above.

  (mac-apple-event [internet-event get-url] ("aevt" ("----" "TEXT" . "mailto:mituharu@math.s.chiba-u.ac.jp?In-Reply-To=wl8y0tjuti.wl%25mituharu%40math.s.chiba-u.ac.jp&Subject=Re%3A%20OS%20X%3A%20using%20emacs%20as%20default%20mailer%3F")))

The patch is also trying to avoid Lisp object allocations (with
respect to Apple events) during asynchronous input handling.
