make sure you add --dns-loop-detect to the command line in /etc/init.d/dnsmasq (I added a line with 'DNSMASQ_OPTS="$DNSMASQ_OPTS --dns-loop-detect"') or you still get cycling after a non-existent host is queried, just not 100% cpu utilization like when both dnsmasq and resolved are running at the same time. In this case, loop detect actually works though.
