How is this supposed to work? Does not dnsmasq (by default) use the
nameserver-entries in /etc/resolv.conf as "upstream" nameservers, to
forward ("non-local") dns-queries to? But what happens if dnsmasq then
forwards a ("non-local") dns-query to 127.0.0.1, i.e to itself? Could
that not result in some kind of infinite loop weirdness?
