Public bug reported:

On startup, the L3 agent looks for namespaces to clean that don't belong
to him, in order to minimize system resources (namespaces) in the
machine.

The fullstack tests run an l3 agent that after deletes some namespaces
that he doesn't know. This in turns causes the deletion of namespaces
used by the functional tests, causing non-deterministic failures at the
gate.

The code in question which is responsible for the deletion of
namespaces:
https://github.com/openstack/neutron/blob/master/neutron/agent/l3/namespace_manager.py#L73

How to replicate:
1. Run 'tox -e dsvm-functional -- neutron.tests.functional.agent.test_l3_agent neutron.tests.fullstack'
2. Some tests are likely to fail
3. ???
4. Profit?

Example of test runs:
1. http://pastebin.com/63n7Y2YK
