We played around with this and it seems fine without it. I think it was added in the original debugging when things were "being added until things works". I don't see any reason it should  be need. But heavens know that isn't safe thinking with casperjs. But I would prefer to try it without it to see if we can simplify. Part of the pain of the current state of the js test suite is that we don't know *why* things work when they do. Cleaning out unnecessary things will help with that.
