Change 95767 by jb at jb_freebsd2 on 2006/04/21 07:09:28

	Add (some? of) the extra variables that DTrace needs in struct proc.
	It likes to get up close and personal with it's buddies.
	
	Adding fields like this raises the issue of how Sun's CDDL applies
	in this case. Should I expect to get permission to do this and retain
	the BSD license. Without that permission, I can't see how doing this
	is legal. And looking at the OpenSolaris distribution and seeing
	AT&T copyright references, I can't help but wonder what a certain
	company in the US south would think about this. Perhaps I should
	just hope they go belly up first. 8-)
