[openstack-dev] [Quantum] New error when creating networks

Any details on what file is being read twice? (I doubt this is a quantum
issue -- more likely to be keystone)

I'm guessing the culprit is that the auth_token middleware reads/writes a
PKI token revocation list to disk... although I'm not sure why it can't be
stored in memory -- Adam?
