Hitting CTRL+C while in Inquirer prompt breaks everything

The output looks like this:

``` js
(^C again to quit)
function (str) {
if (str === undefined) {
return this._delimiter;
}
this._delimiter = String(str).trim() + ' ';
if (this.isLocal()) {
this.parent.ui.refresh();
} else {
this.parent._send('vantage-delimiter-downstream', 'downstream', {value: str, sessionId: this.id});
}
return this;
}
_
```

You can still type but nothing happens. Only way to recover is hitting CTRL+C again.
