If I add !?DUP into my x86 primatives, I can do:

\ ( u xt lh -- ln | 0)
\ xt api is ( u ln lh -- ln | 0 )
: LISTHEAD-ENUMERATE-FORWARDS
	DUP DUP LISTHEAD-GET-HEAD
	BEGIN
		NIP DUP LISTNODE-GET-SUCC !?DUP
	WHILE
		4 PICK 2 PICK 4 PICK
		6 PICK EXECUTE ?DUP
	UNTIL THEN
	2NIP 2NIP NIP
;

Which I think is nicer ? I'm still not convinced about not useing PICK 
! It avoids doing rot and swaps to just marshal paramaters, and using 
the return stack rather than 6 PICK is not faster.
