This patch prevents the following error: AltDataOutputStreamChild::Close -> SendClose() AltDataOutputStreamChild::Release -> Send__delete__() AltDataOutputStreamParent::RecvClose() -> SendError() AltDataOutputStreamParent::ActorDestroy -> mIPCOpen = false AltDataOutputStreamChild::RecvError -> === Crash - object was deleted === We introduce the DeleteSelf message. AltDataOutputStreamChild::Release -> SendDeleteSelf() AltDataOutputStreamParent::RecvDeleteSelf -> mIPCOpen = false; SendDeleteSelf() AltDataOutputStreamChild::RecvDeleteSelf -> Send__delete__() The parent will not send any more messages after receiving the DeleteSelf message.
