      The QDnsLookupThreadPool::signalsConnected boolean variable is written to and read from outside signalsMutex protection in _q_applicationDestroyed() and start(QRunnable*). This is a data race, because the writes don't synchronize-with the reads.

      QTBUG-113836 fixed this for 6.6+, but Qt ≤ 6.5 is still affected.
