Ah, Xan and I were talking about this yesterday.

One tricky bit; SoupAddress no longer caches DNS results itself, so what you
are testing here is not "libsoup has to do DNS" vs "libsoup does not have to do
DNS", but rather "libsoup has to do DNS and the upstream caching DNS server has
to query the net for the answer" vs "libsoup has to do DNS and the upstream
caching DNS server already has the answer cached".

SoupSession does cache SoupAddresses, so if you could change prefetchDNS() to
resolve the session's SoupAddress for that hostname rather than creating its
own, then that would probably improve the results a bit more. There's no way to
do that currently though; this would require some new libsoup API.
