	* gtk/gtktreeselection.c (gtk_tree_selection_selected_foreach): quit
	maintaining the iter on every iteration, only get the iter when
	we are about to call the foreach_func. Gives us a 10x speedup,
	since maintaining iters is a lot more expensive than maintaining
	paths. We lose a bit of sanity checking though. Thanks go to
	Billy Biggs for pointing this out.
