	Peter, how was this productive to the discussion?  "usually
	the only address in use" does not preclude the use of other
	addresses.  I use other addresses under 127/8 myself but I
	am also atypical in this respect.

	The discussion was what to name these other addresses and
	I was saying don't name them "localhost".
