Hmm. I'd forgotten that the setgid kmem was removed in 4.x; I was
probably thinking of top, which still is setgid in -STABLE. You'll find
however, that -e won't work without setgid kmem being turned on. There
are a number of other tools in -CURRENT that aren't setgid kmem where they
are in -STABLE (top, iostat, etc).
