  While investigating CVE-2014-8124
  (https://bugs.launchpad.net/horizon/+bug/1394370) I think I found
  another instance of the underlying issue, but with the logout form.
  
  I'm on Ubuntu 14.04 LTS, with distro-packaged openstack-dashboard
  1:2014.1.4-0ubuntu2. I verified the patch from
  https://review.openstack.org/140356 is applied to the installed files. I
  configured horizon to use mysql datastore, and ran the following
  command:
  
  while true ; do wget http://localhost/horizon/auth/logout/ ; done
  
  While this command was running I checked the mysql dash database table
  django_sessions and found it growing without apparent bound:
  
  select * from django_session;
  ...
  231 rows in set (0.00 sec)
  
  Is this an issue?
  
  Thanks
