It's often done by nginx if the backend doesn't send any bytes in the response in a certain amount of time. Gunicorn may have similar settings.

I think it's more complicated than a boolean field because you need a compare-and-set operation that is atomic. redis.io/topics/distlock has some information about using redis to do locking.
