bug#1578: emacsclient -c make emacs very slow (under Mac OSX)

Odd: I'm not a regular Mac OS X user, but from the little bit of
exposure I've had to this system, I would have expected the exact
opposite: I'd have expected "emacs --daemon" to bring up the Emacs icon
in the dock even before the first frame is opened, and would stay there
until the daemon exits.
