-- Agregar timeouts (recvtimeout y sendtimeout).
+- Agregar timeouts (recvtimeout() y sendtimeout()).
- Darle bola al header Connection para saber si cerramos la conexión al
finalizar el request o no.
-- Ver por que el ControlClient tira una señal de error despues de una respuesta
- buena.
+- Hacer un try/catch en cada llamada al socket por si se desconecto, para que no
+ muera con un segmentation fault.
