Public bug reported:
The debug tracepoint in Dnsmasq._output_hosts_file is extraneous and
causes unnecessary performance overhead due to string formating when
creating lots (> 1000) ports at one time.
The trace point is unnecessary since the data is being written to disk
and the file can be examined in a worst case scenario. The added
performance overhead is an order of magnitude in difference (~.5 seconds
versus ~.05 seconds at 1500 ports).
