TL;DR - We really need reliable tests for the exact behavior we want before coming up with patches.

attached is a patch (-gps01) that would do the same thing as Lib/smtpd.py does... But I'm not convinced it is a good idea.

Would forcing a socket.getaddrinfo() call from the constructor cause problems?  This would be new behavior over what TCPServer did in the past.  Could it trigger a blocking reverse DNS lookup where there wasn't one in the past?

What about when server_address[0] is ''?  getaddrinfo() fails on that, but the existing code works and binds to 0.0.0.0.  Presumably this should bind via AF_INET6 if the host supports it but a simple getaddrinfo() call doesn't tell us that.
