[$] Seccomp and deep argument inspection

Kees Cook has been doing some thinking about plans for new seccomp features to work on soon. There werefour separate areas that he was interested in, which he detailed in alengthy mid-May message on the linux-kernel mailing list. One of thosefeatures, deep argument inspection, has been covered here before, but it would seem that weare getting closer to a resolution on how that all will work.
