I read that getaddrinfo() returns addresses sorted based on RFC 3484. I'm
using the attached program to test it and I'm not sure if they are sorted.

I looked at the musl getaddrinfo.c here:
https://github.com/idunham/musl/blob/master/src/network/getaddrinfo.c

I don't see an obvious sort in the code. Is it there?
