+ * For details on the Windows XP logout process, see:

+ *
+ * Vista adds some new APIs which EggSMClient does not make use of; see
+ * http://msdn.microsoft.com/en-us/library/ms700677(VS.85).aspx
+ *
+ * When shutting down, Windows sends every top-level window a
+ * WM_QUERYENDSESSION event, which the application must respond to
+ * synchronously, saying whether or not it will quit. To avoid main
+ * loop re-entrancy problems (and to avoid having to muck about too
+ * much with the guts of the gdk-win32 main loop), we watch for this
+ * event in a separate thread, which then signals the main thread and
+ * waits for the main thread to handle the event. Since we don't want
+ * to require g_thread_init() to be called, we do this all using
+ * Windows-specific thread methods.
+ *
+ * After the application handles the WM_QUERYENDSESSION event,
+ * Windows then sends it a WM_ENDSESSION event with a TRUE or FALSE
+ * parameter indicating whether the session is or is not actually
+ * going to end now. We handle this from the other thread as well.
+ *
+ * As mentioned above, Vista introduces several additional new APIs
+ * that don't fit into the (current) EggSMClient API. Windows also has
+ * an entirely separate shutdown-notification scheme for non-GUI apps,
+ * which we also don't handle here.
