there is no "spec" on how it should be done. Again, it is about security and "doing it as right as possible" and not "according to POSICKS we can do whatever we want".
Just necause some standard says we needn't does not mean that we could do it better.

It is possible to get "good enough" semantics with the special-marked-library solution (I think), but I also fear this solution will be quite fragile in practise (because I dislike concepts like setuid-libraries since they scored very low in history).
