gunicorn se cierra por timeout

[FranFunes]

• Aplicación iniciada, sin otras acciones de por medio.
• Navegador abierto en /tasks.
• Una única tarea en la base de datos.
• Los requests a /get_tasks_table se resuelven sin problemas, hasta que uno se demora y falla.
• En el log de la app se ve: petfectior-client-dev | [2024-09-13 16:32:27 -0300] [1] [CRITICAL] WORKER TIMEOUT (pid:153)

El uso de cpu de la app es demasiado alto (entre 75% y 80%), incluso cuando no está haciendo nada. Probablemente se deba a algún while que no está limitado.

[FranFunes]

Deteniendo cada proceso por separado, encontré que el consumo de cpu está en el Task Manager, cuyo main loop se ejecuta continuamente si existe alguna tarea. Esto también podría estar relacionado con el issue #59, dado que Task Manager está leyendo continuamente la tabla Task, bloqueando la base de datos.
