[issue38884] __import__ is not thread-safe on Python 3

I believe I'm also encountering some version of this bug while importing code from the kombu library within a multi-threaded context.

For what it's worth, I'm able to reproduce the reported deadlock (https://bugs.python.org/file48737/issue38884.zip) using python3.8 on RHEL8 and CentOS 8 builds.

More details about what I'm encountering here: https://github.com/ansible/awx/issues/5617
https://github.com/ansible/awx/issues/5617#issuecomment-591618205

My intended workaround for now is to just not use a thread (we'll see if it helps):
