Problem: running python-memcached tests with tox fail on obvious Python 3 errors. Anyway, all tests now pass with my pull request. The good news is that python-memcached looks to be actively developed.

Yes please to using pymemcache (I'm also an active contributor[1] there, 
so feel free to ask me questions to...), although what else in openstack 
uses it? From my current understand the nova usage of it is suboptimal 
(may not even be fully working/functional) due to: 
https://review.openstack.org/#/c/138607/ which has exposed some 
interesting details...
