-------------------------------------

This is not resolved, the attached PR was never really reviewed and closed due to inactivity.  We continue to run similar code in our own fork.

> The dataflow runner collects (and publishes to the dataflow service) a large number of useful stats.  While these can be polled from the dataflow service via its API, there are a few downsides to this:
>  * it requires another process to poll and collect the stats
>  * the stats are aggregated across all workers, so per-worker stats are lost
> It would be simple to provide a hook to allow users to receive stats updates as well, and then do whatever they want with them.
