That is much better :-)  Still, lots of gethostbyname()->getaddrinfo()
conversions were done blindly and the ammount of bugs re. DNS round-robin
this will expose is not funny.

Is there any advantage for that default in Debian?  Anyone who cares about
network proximity on round-robin IPv4 already knows to pick one host and
to stop using the round-robin names.

We still ship ECN disabled for a reason, and unlike ECN enabled by default
everywhere (which would actually help a lot the network), breaking IPv4
round-robin in buggy applications will only make things worse (as our
default is NOT going to find out the closest IPv4 host automatically).
