//
// A clean exit happens when the SignalInterrupt object is triggered, which
// makes the main thread's SignalInterrupt::wait() call return, and join all

// Shutdown() is then called to clean up database connections, and stop other
// threads that should only be stopped after the main network-processing
// threads have exited.
//
// Shutdown for Qt is very similar, only it uses a QTimer to detect
// ShutdownRequested() getting set, and then does the normal Qt
// shutdown thing.
