Killing process trees

child.js

var PORT = 8080;

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

parent.js

var spawn = require('child_process').spawn;

process.on('exit', killChild.bind('exit'));
process.on('SIGTERM', killChild.bind('SIGTERM'));
process.on('SIGINT', killChild.bind('SIGINT'));

test.js
