    Catch socket.timeout when doing heartbeat_check

    heartbeat_check in kombu.connection is not reraising exceptions as
    exceptions.OperationalError, and the socket timeout during the heartbeat
    check is really an issue seen in the field when a node goes down; the
    heartbeat thread just tries again and again to deal with it, without
    success.
