Comment 1 for bug 1635449

We believe that this may be due to https://github.com/openstack/neutron-lbaas/blob/master/neutron_lbaas/services/loadbalancer/plugin.py#L537-L543 performing test_and_set_status first and then creating the listener while https://github.com/openstack/neutron-lbaas/blob/master/neutron_lbaas/services/loadbalancer/plugin.py#L668-L671 creates the pool first and then performs the test_and_set_status.

We suspect that the listener creation puts it into pending update while it is setting that up, but the pools keep creating until it finally completes successfully (after the status goes back active)
