i think that the hybrid ipv4-ipv6 stack architecture is the best choice
at this moment. maybe when we'll have a 99% ipv6 internet it will make
any sense to have a real dual stack architecture (so that you can disable
ipv4), but in this moment i think that splitting common ipv4-ipv6 code
in the linux kernel would be a mistake.

yes, really.
