Subject: [PATCH] Avoid using GREENDNS due to dnspython

If dnspython is present in your environment then
eventlet monkeypatches socket.getaddrinfo() with an implementation
which doesn't work for IPv6. To turn this off you need to set an
environment variable before you do the import.

Resolves bug 1164822
