Gio.DBusConnection.exit_on_close
DBusConnection.exit_on_close: Boolean (Read / Write)
A boolean specifying whether the process will be terminated (by calling `raise(SIGTERM)`) if the connection is closed by the remote peer.
Note that Gio.DBusConnection objects returned by Gio.bus_get_finish and Gio.bus_get_sync will (usually) have this property set to true.
