I have a simple test client that performs load tests against a REST service 
with http.request, essentially executing the following inside of a big loop

  var body = 'whatever=something';

  var options = {
    hostname: 'my.api.server',
    port: 1234,
    path: '/api/that/i/want/to/test',
    method: 'POST',
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded',
      'Content-Length': body.length
    }
  };

  var req = http.request(options, function(res) {
    console.log(res.statusCode);
    res.emit('end'); // force the connection to close (IS THIS REALLY 
CORRECT?)
  });
  req.end(body);

If the server is configured to send the Connection: close header (or if I 
include the res.emit('end')line) this works fine.  However if the server 
doesn't send that header (and e.g. restify doesn't by default) my client 
stops getting responses after about 5 requests have been sent.  The emit 
trick was gleaned from here

But is this really the "node correct" way to do this?
