Evita el manejo de finalizaci\u00f3n forzada en una entrada a la que a\u00fan no se le ha asignado un \u00edndice, lo que provoca un acceso fuera de los l\u00edmites en idx = -22. En lugar de esperar indefinidamente el sem, el flujo de bloqueo ahora espera a que se asigne el \u00edndice o a que se agote el tiempo de espera de adquisici\u00f3n del sem antes de iniciar el temporizador para completar el FW.
