You keep saying this yet everytime I ask for an example I get nothing. > reduce the need for register-clobbering barriers, shrink our binaries, > shrink our code, improve performance, and avoid heisenbugs, I think it's > a win, whether or not we *need* it. Hmm, you're increasing our binary size and probably killing performance.
