// 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 triggers
// the DetectShutdownThread(), which interrupts the main thread group.
// DetectShutdownThread() then exits, which causes AppInit() to
// continue (it .joins the shutdown 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.
//
// Note that if running -daemon the parent process returns from AppInit2
// before adding any threads to the threadGroup, so .join_all() returns
// immediately and the parent exits from main().
//
// Shutdown for Qt is very similar, only it uses a QTimer to detect
// fRequestShutdown getting set, and then does the normal Qt
// shutdown thing.
