Cause: Multiple bugs
Consequence: When deleting a Namespace that contained NetworkPolicies, some of the OVS rules pertaining to those NetworkPolicies did not get cleaned up. While these rules were harmless in themselves (they wouldn't cause any packets to be mistakenly accepted or rejected), it is possible that the build-up of junk rules might have eventually caused slowdowns. (But note that we are not aware of any customers actually experiencing problems because of this at this time.)
Fix: All OVS flows associated with a Namespace should now be deleted properly when that Namespace is deleted.
Result: No problems
