Is this waiting part necessary?

[allanwakes]

for this notebook: ex_04_remote_classes_revisited.ipynb.
In [6]: Let for the workers to finish by returning their DONE state.
My question is:
1)
values = ray.get(results), this is a block action. values are all set and determined once all models done their jobs and returned results.
so that loop is not needed.
2)
in that loop itself, values are never changed (regained from models)
so that loop is not needed (will not end?)

Thanks for this tutorial!
