Comment 16 for bug 1597596

@Jesse Ok, that matches what I am seeing, thanks for confirming. If you still have some of these instances online, you could also check in the nova DB whether any of them have entries for 'network_allocated' in the system_metadata table (cf. https://bugs.launchpad.net/nova/+bug/1597596/comments/7). Assuming there are none, that would undermine my assumption that these async processes are not executed in the way described in the code.
