Sigh.

My tests only use

local_interfaces = <; 127.0.0.7 ; ::1

and that works on Solaris 8. I will try testing with other values, just
to make sure it's not something general that I have screwed up.

Since getaddrinfo() is now called in just one place, changing it should
be relatively simple.

But I'm also waiting to hear if other people hit this problem...
