This is probably right..
I don't know why you are seeing such weirdness however. Is your world and
kernel out of sync. It's a nice (mis)feature now that if items in the middle
of kinfo_proc change size it still tries to use the misordered data rather than
complaining about it like it used to. :-P See my other e-mail where top on my
laptop doles out time to userland tasks ok.

I agree.
