	 * blocking IO. This means that it is appropriate to call e.g.
	 * [polkit_authority_check_authorization_sync()](http://hal.freedesktop.org/docs/polkit/PolkitAuthority.html#polkit-authority-check-authorization-sync)
	 * with the

	 * If %FALSE is returned then no further handlers are run and the
	 * signal handler must take a reference to @invocation and finish
	 * handling the call (e.g. return an error via
	 * g_dbus_method_invocation_return_error()).

	 * Otherwise, if %TRUE is returned, signal emission continues. If no

	 * #GDBusObjectSkeleton::authorize-method signal handlers run before
	 * the handlers for this signal.
	 *
	 * The default class handler just returns %TRUE.
	 *
	 * Please note that the common case is optimized: if no signals
	 * handlers are connected and the default class handler isn't
	 * overridden (for both @interface and the enclosing
	 * #GDBusObjectSkeleton, if any) and #GDBusInterfaceSkeleton:g-flags does

	 * flags set, no dedicated thread is ever used and the call will be
