prediction-flavored outputs, in addition to the classification-flavored one.
    Building signatures from these allows TF Serving to honor requests using the
    different APIs (Classify, Regress, and Predict). Furthermore,
    `serving_input_receiver_fn()` may now specify alternative subsets of nodes
    that may act as inputs. This allows, for instance, producing a prediction

En lugar de eso, al ser un sistema "asíncrono", una vez terminado, la tarea puede esperar un poco en la cola (algunos microsegundos) para que la computadora / programa termine lo que salió a hacer, y luego regrese para tomar los resultados y continuar trabajando con ellos.
