   No, really! __Sharing__ of port space between IPv4 and IPv6 was mad
   idea. It cannot generalized to other protocol families.
   
   So, IPV6_V6ONLY is really unique for IPv6. Well, actually, it could
   be negated: be default and the option would be called
   IPV6_SHARE_THIS_PORT_TO_IPV4.

I think what I want to really say is that I want to provide
way for ipv4 application to say "no ipv6 connections on this
listening socket please".

So does it make no sense at all to have IP_V4ONLY?
