Bug#1042466: AttributeError: module 'eventlet.green.select' has no attribute 'epoll'

[Gregor Riepl]

Here's a temporary workaround until the issue is fixed.
Either set the environment variable EVENTLET_NO_GREENDNS to "yes" before 
launching applications that import eventlet, or put the following Python 
code before loading the module:

import os
os.environ['EVENTLET_NO_GREENDNS'] = 'yes'
import eventlet
...
