There's an additional benefit for high-traffic reverse proxy installations
(for example, sites that use nginx as a load balancer) : with keepalive
connections, there's less risk of running out of ephemeral port numbers - or
less need to decrease the TIME_WAIT interval to free up ephemeral port
numbers faster.
