I second the statement about multi-threading headaches if you use globals in this way.
In Aquarium, since I have to support different threading API's (no threads, Python threads, coroutines), I put everything in a Context object, and then pass that Context object to everything's constructor. This isn't as bad as it sounds. It happens automatically when I call aquariumFactory(moduleName, *args, **kargs) which does a dynamic import, instantiates the class passing the Context object and the additional args, and then returns the instance.
