I initially reported this on launchpad at https://bugs.launchpad.net/bugs/1782647.

I'm running a test for a project that hangs and requires a Control-C to cancel it. The results look like this: https://paste.ubuntu.com/p/SwXsCcghjt/

In narrowing down on this some more, the use of queue.SimpleQueue() seems to make the difference that causes the hang. If I switch that back to queue.Queue() (which was the case for py3.6) the hang goes away:

- self._work_queue = queue.Queue()
+ self._work_queue = queue.SimpleQueue()

To reproduce with OpenStack designate:

git clone https://github.com/openstack/designate.

Then, update tox.ini with the following:

--- a/tox.ini
