Okay, my answer does not directly answer the OP's question. But as this shows up in the top search results for the error AttributeError: 'XxxxxHandler' object has no attribute 'async_callback'

It is worth noting that starting Tornado v4.0 the async_callback function has been removed. To quote the Backwards-compatibility notes:

The RequestHandler.async_callback and WebSocketHandler.async_callback wrapper functions have been removed; they have been obsolete for a long time due to stack contexts (and more recently coroutines).
