Comment 3 for bug 1347156

I've verified that the quota value listed in the quota_usages table does not correctly track allocation and usage. Values increment properly on nova floating-ip-create but are not decremented when nova floating-ip-delete is called. Other values appear to be being managed properly.

Steps to verify:

repeat 11 times:
- create a floating ip
- delete allocated floating ip

Exception will occur
select in_use from nova.quota_usages where resource = "floating_ips";

will return 10 or whatever the current floating IP quota is.
