    Eventlet green threads not released back to pool

    Presently, the wsgi server allows persist connections. Hence even after
    the response is sent to the client, it doesn't close the client socket
    connection. Because of this problem, the green thread is not released
    back to the pool.

    In order to close the client socket connection explicitly after the
    response is sent and read successfully by the client, you simply have to
    set keepalive to False when you create a wsgi server.

    Icehouse backport note: socket_timeout was dropped, it was introduced
    in 0.14[*] and Icehouse eventlet lower bound is 0.13
