### Summary

In several collection CIs, @briantist and me noticed that `ERROR! A worker was found in a dead state` started showing up a lot more often since < 24 h, but only with Python 3.5.

In the CIs I've observed this in, `ansible-test` is invoked with `ansible-test integration -v --color --retry-on-error --continue-on-error --diff --python 3.5 --docker` and running itself under Python 3.8.
