// Shutdown
//

//
// Thread management and startup/shutdown:
//
// The network-processing threads are all part of a thread group
// created by AppInit() or the Qt main() function.
//
// A clean exit happens when StartShutdown() or the SIGTERM
// signal handler sets ShutdownRequested(), which makes main thread's
// WaitForShutdown() interrupts the thread group.
// And then, WaitForShutdown() makes all other on-going threads
// in the thread group join the main thread.
// 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.
