I can't fully agree with this:

>Monitoring and managing consumers is another (mostly orthogonal) realm.
Monitoring of consumers is already added via task_done() and join() methods. At least this two methods allows to understand that all consumers are in idle state.
The unfinished() - is just functional extension to this existing functionality.

This sounds reasonable because I also understand that this method is not usable in all cases as in most cases task_done is not used.
Probably my idea for method unfinished is really not so good...
Actually I've manage to find unpublished Queue.unfinished_tasks variable just in several minutes when I tried to find solution for threaded PoolExecutor. Hope that any curious developer can find it too.
I don't mind if you close this CR.
Thanks for pleasant discussion.
