+// 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().
