The shutdown system test sends queries when named is shutting down, not in an attempt to get answers but to destabilize the server into a crash. With isctest.query.udp() defaulting to try up to ten times with a ten-second timeout to get a response we don't care about from a likely terminated server, we make the test run much longer than needed because of retries and long timeouts.
