> From tornadoweb (applies to deft also):
> http.fetch("http://friendfeed-api.com/v2/feed/bret";,
> callback=self.async_callback(self.on_response))
> "If you make calls to asynchronous library functions that require a callback
> (like the HTTP fetch function above), you should always wrap your callbacks
> with self.async_callback. This simple wrapper ensures that if your callback
> function raises an exception or has a programming error, a proper HTTP error
> response will be sent to the browser, and the connection will be properly
> closed."
> The async_callback wrapper function is removed in new tornado releases (>
> ~0.2.0), instead contextmanagers are used (not applicable to java, could be
> available in jdk7 with TWR).
