That is true, but the DNS server also does a round-robin ordering of 
addresses to spread the load on identical servers. getaddrinfo() is 
kind-of smart, but it can't tell the difference between two global IP 
addresses of the same version (v4 or v6).

Anyways, since the cache is held per application, this is not a big 
problem -- or a problem at all.

Patch is good, perfectly indented, very clever. Please commit!
