Good news: the just released eventlet 0.17.3 includes these fixes and it is now fully compatible with Python 3! For example, the Oslo Messaging test suite now pass with this eventlet version! Currently, eventlet is disabled in Oslo Messaging on Python 3 (eventlet tests are skipped).

Also, on the Python 3 topic, there's still a big issue with memcached 
(aka: python-memcache). It's blocking me from adding Python3 support to 
keystoneclient, and as a consequence, to almost all of OpenStack.

BTW, the Eventlet module for 0.17.3 is available from here:

and I will upload this to Experimental as soon as Jessie is released 
(that's in 3 days now...).
