> Some reverse proxies (e.g., ELB using an HTTP listener) won't close the upstream connection
to Mesos when they detect that their client is disconnected.
> This can make Mesos leak subscribers, which generates unnecessary authorization requests
and affects performance.
> We should evaluate methods (e.g., heartbeats) to enable Mesos to detect that a subscriber
is gone, even if the TCP connection is still open.
