Using self.response.out will also delay sending your entire response until it is sure to succeed.
If you start generating output using 'print', and then e.g. a Datastore request times out, or a bug in your code is triggered, you have no chance to display a friendly error message. Instead the user will get a half-rendered page with a stack trace embedded in it, or worse.
