it's not a bad idea that it should be shipped...]

Exactly. Owner root, mode 0500. Problem solved?
Just because Stun ships their version as root.kmem, 02755,
doesn't mean everyone else should do the same thing.
However, I agree; the utility of this kind of tool is
limited to, maybe, "do a memory check", and more likely,
"run this program to see some VM bugs", or even, "run this
program to simulate EMACS making a computer slow".
I doubt the last two things are very useful at this point,
and I'm sure that reaching out and dirtying lots of VM pages
certainly isn't a good way to check physical memory...
