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.
