I agreed until we started with this 'procfs' thing. With ps sgid kmem and pulling data from /dev/kmem, the appropriate place to put the limit was in ps. With /procfs (and presumably a similar desire to limit data leaking), presumably the kernel would also be involved in limiting the spread of info. Perhaps we can get ps to only use procfs and that would be far more desirable than this kmem approach. I guess one would also have to either limit top, or have top use procfs.
