	PROFILE: new! improved! with extra CONSing!
	...uses UNWIND-PROTECT so that functions with nonlocal exit
		don't appear to be free (with thanks to Dan Barlow for
		pointing out that UNWIND-PROTECT didn't need to be
		reimplemented:-)
	...handles fixnum overflow in DCONSING (which was pointed out
		by Antonio Martinez)
	(Hopefully the correctness increase is worth the increased
		consing (by UNWIND-PROTECT) on every call. If not,
		comments/suggestions welcome.)
