[issue20319] concurrent.futures.wait() can block forever even if Futures have completed

Any ideas how to debug this further?

In order to overcome this issue I have an awful workaround that tracks the maximum running time of a successful task, and if any task has been running more than x times that maximum I consider it defunct, and increase the number of concurrent allowed tasks. However, if the problem persist, I eventually will have lot of zombie tasks, which will expose some additional problems.
