 // 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
 // fRequestShutdown, 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.
