The part I wasn't sure about is whether there was any known entity that would pick the branch update up, and rebuild with it. Nevertheless, this is not critical at all. As long as the patch is extra safe (which it looks like it can't possibly cause things to be worse, except in the pauth case which is already crashing), I don't see a reason why we should block the patch's inclusion in our older branches. You can go right ahead. -- Joel
