To quit the thread, connect the worker's destroyed() signal to the thread's quit() slot. Then just deleteLater the worker.</pre>

The code has a race condition in which wait() returns false, then we switch to the thread and m_autoDelete is still not set and thus noone will delete the thread. I can add a mutex if you guys think this is unacceptable.</pre>
