Yup, I'd forgotten that little Tale of Terror from 4.0 development days.
If you have to do something like

	if (foo->bar->bletch == mem_rop) {
		/*
		 * Do special memory pixrect stuff
		 */
	} else {
		/*
		 * Do other pixrect stuff
		 */
	}

this comes into play (i.e., it's not *any* reference by name that causes
problems, it's references that actually care about the address of the
function as something other than the target of a jump).
