Comment 12 for bug 1790569

All open patches have been abandoned so I'm marking this incomplete and removing the assignee. I don't doubt this is something that could happen to leak allocations, but we'd need a more specific recreate I think. As a workaround, the operator could use the osc-placement CLIs to cleanup the unwanted allocations, or delete all allocations for the instance and then run the 'nova-manage placement heal_allocations' command to correct the allocations for the instance in placement.
