* dbus-connection.c (dbus_connection_send_with_reply): return TRUE
and set pending_reply out arg to NULL is connection is disconnected (connection_timeout_and_complete_all_pending_calls_unlocked): New static method for cleaning up pending calls on disconnect (_dbus_connection_get_dispatch_status_unlocked): If we have pending calls queued timeouts on disconnect * dbus/dbus-pending-call.ci (_dbus_pending_call_set_connection): Remove
