It is not necessary (and quite wrong) to implement RR in the server.
It's an approximation at best anyway.  In no way better than
randomization.  And nothing stops programs from randomizing the results
returned by getaddrinfo before using them.  Normal programs won't do
that but there is nothing which stops programs like ntpd from doing this.
