So I'm literally saying that it had better really *be* independent from /proc. It is the standalone version, but it's most definitely also the version that doesn't then give you secret access to /proc. And it weorries me a lot that people are trying to play these kinds of games. I'm just seeing some android patch that adds this horror and then starts using it. Linus
