Change 9996 by rwatson@rwatson_tislabs on 2002/04/19 06:36:48

	Pro-active diff reduction.
	
	Restructure the proc0/proc1 credential divorcing to reflect the
	crcopy() approach now used in the main tree.  This is identical
	to the code committed to the main tree a few minutes ago, and
	reduces diffs between the trees.
