Bug description:
[Impact]
This appears to be the same issue documented here: https://github.com/eventlet/eventlet/issues/592
However I seem to only hit this with python3.8. Basically nova,
glance, neutron, and cinder services fail with:
Exception ignored in: <function _after_fork at 0x7f1100d075e0>
Traceback (most recent call last):
File "/usr/lib/python3.8/threading.py", line 1454, in _after_fork
assert len(_active) == 1
AssertionError:

Patching nova/monkey_patch.py with the following appears to fix this:
diff --git a/nova/monkey_patch.py b/nova/monkey_patch.py

Similar patches to glance/cmd/api.py, glance/cmd/scrubber.py and
glance/cmd/registry.py appears to fix it for glance.
[Test Case]
'systemctl status <service>' should not show the failure reported in [Impact].
[Regression Potential]
Should be low. The fix provided is a well-known solution to the problem. Openstack deployment + tempest regression testing will be performed to help reduce regression potential.
