Hi all,

I've put together an illustrative example of this at 
https://gitlab.com/BuildStream/buildstream/merge_requests/1482.

Unfortunately, I didn't have time to put together an example of progress 
reporting for long-running tasks that run in subprocesses, but it does 
manage to show off:
* A relatively simple contextmanager for setting progress information in 
a long-running task.
  - That logs when it starts and finishes (with the progress information 
at the time it finished)
  - And render updates are throttled to once per second.

Thanks all,

Jonathan
