Actually, I am wrong about DNS here. We use a bare 127.0.0.1 in
lib-httpd.sh, so DNS may indeed be the source of the issue here. That
_might_ mean that using the bare IP would be safe here, but I would not
want to bet on it. Using different port numbers, plus not expecting a
listener on the other end, might cause different outcomes than we see in
the other tests.
I do think moving these tests to use a real http server is a better
solution, though. I'll provide a patch in a moment.
