node.js windows spawn with cmd /s /c

1 test.js

var http = require('http');
var spawn = require('child_process').spawn;
var child = spawn(
  'CMD', [
    '/S',
    '/C',
    'node',
    './child.js'
  ]
);
child.stdout.pipe(process.stdout);
child.stderr.pipe(process.stderr);

child.on('exit', function() {
  http.get('http://localhost:8080', function(response) {
    console.log('child did NOT die');
  }).on('error', function(error) {
    console.log('child did die');
  });
});

setTimeout(function() {
  http.get('http://localhost:8080', function(response) {
    response.on('end', function() {
      console.log('kill the child');
      child.kill();
    });
  });
}, 2000);

2 child.js

var http = require('http');

var PORT = 8080;

var server = http.createServer(function(request, response) {
  response.end();
});
server.listen(PORT, function() {
  console.log('Listening on port ' + PORT);
});

3 output

V:\GitHub\node-ChildDaemon\test\Spikes\windows>node test.js
Listening on port 8080
kill the child
child did NOT die


*********
I can kill the process and children with ctrl-c at this point (although i expected it to kill the child and exit on it's own)
