code: function bindReqSocket(req, socket) {
    //gReqCount++;
    req.onSocket(socket);
    socket._reqCount++;
    socket._used = true;
    timers.unenroll(socket._kpTimer);
  }
docs: Another departure is that all code related to HTTP parsing is in ClientRequest.onSocket(). The Agent is now *strictly* concerned with managing a connection pool.
