 I had a look at your patch, most of it looks fine, but you add
 std::exception as a base class of boost::thread_interrupted. That is a
 very bad idea, boost::thread_interrupted should not derive from any other
 type, so that normal exception-handling code will not interfere with
 interruption handling.

 while (true)
     lock_guard<mutex> lock(m_mutex);
   catch (std::exception& e)
      std::cerr << "Error processing queue: " << e.what() << '\n';
 Currently this loop can be stopped by interrupting the thread, with your
 change it cannot.
