Alan,
Don't assume sockets will default to dual stack, explicitly set
IPV6_V6ONLY to 0. Apparently some Linux distros ship with
net.ipv6.bindv6only=1 restricting sending and receiving to IPv6
packets only. Changes both net and nio code.

Thanks,

The changes look okay to me. I assume the bulk of our existing tests
will fail if we run on a system has IPV6_V6ONLY enabled by default (and
so a new test isn't required for this fix). One small suggestion is just
to add a comment to explain why the socket option needs to be disabled.
