I like this a lot. This addresses a very serious gap in the sockets
API, and should be very useful. The comment mentions that this is
available for IPv6. From skimming the change I would have expected
inet6_bind() would need a change analogous to the change in
inet_bind()? Was there a missing "git add", or is a change to
inet6_bind() somehow not needed?

Thanks!
