`naught stop` not working.

`naught start example.js`
`naught stop`

Child process fails to receive process.on('message', ...) in node v0.11.11 and greater.

```
if (process.send) {
process.send('online');
console.log("sent online");
}

process.on('message', function(m, server) {
//********** This never gets called in node v0.11.11 or greater. **********
console.log('Message' + m);
process.exit();
});

var number = 0;
function printMessage() {
number = number + 1;
console.log("Message " + number);
setTimeout(printMessage, 1000);
}
printMessage();
```
