      Description

        The default idle time for SO_KEEPALIVE is 2 hours, too long for most applications. Some operation systems have support to configure the idle time on a per connection basis (Linux has TCP_KEEPIDLE, Windows has SIO_KEEPALIVE_VALS). We should consider exposing an extended socket option to configure this.
