Interestingly, I found this bit of code over in the libX11 code in
_XConnectXCB in xcb_disp.c:

	if(!display || !*display) display = getenv("DISPLAY");

	if(display && strlen(display)>11 && !strncmp(display, "/tmp/launch", 11)) {
		/* do nothing -- the magic happens inside of xcb_connect */
	} else

The libX11 code is already expecting xcb_connect to handle the launchd
(MacOS) special case.

Maybe I'm  missing something about what's happening in xcb_connect, then.
