+// 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().
+//

+// fRequestShutdown getting set, and then does the normal Qt
+// shutdown thing.
