- * If we are about to die we must call i9e_close() to reset the terminal.
- * However, i9e_close() must be called in *this* context, i.e. from
- * play_task.post_monitor() rather than from i9e_post_monitor(), because
- * otherwise i9e would access freed memory upon return. So the play task must
- * stay alive until the i9e task terminates.
- *
- * We achieve this by sending a fake SIGTERM signal via i9e_signal_dispatch()
- * and reschedule. In the next iteration, i9e->post_monitor returns an error and
- * terminates. Subsequent calls to i9e_get_error() then return negative and we
- * are allowed to call i9e_close() and terminate as well.
