Setting this too low has the risk of shutting down the Mesos driver (and thereby killing the spark executors) while the executor is still in the process of exiting cleanly. --- End diff -- actually, I would probably not document this config. I don't really see a use case where users would want to change this. If we decide that users do want to control this (which I don't think they will) then we can always expose it later, but we can't go the other way because of backward compatibility.
