The environment module will be configured once, during code initialization. Subsequently all other possibly-evented modules will retrieve from environment and transparently obtain either the eventlet or standard library modules. If eventlet, httplib, subprocess or other environment dependant module is referenced outside of the environment module it should be considered a bug. The changes to tests are required to ensure that test is imported first to setup the environment. Hopefully these can all be replaced with an __init__.py in a post-nose keystone. Implements: blueprint extract-eventlet Change-Id: Icacd6f2ee0906ac5d303777c1f87a184f38283bf
