I don't want, necessarily, to have slower code to make handling corner cases easier. However, I am generally happy to have slower code in return for making the system more secure, as long as the speed hit isn't too substantial. Security is a much bigger problem than performance right now for most people. The hard part is distinguishing between those two properties. -- Russ Allbery (r...@debian.org) <http://www.eyrie.org/~eagle/> -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
