Looks like a good fix for now.
I would eventually really like to get rid of the `GlobalConfiguration`
singleton - it causes issues with embedding, testing, and encourages to not
cleanly think through designs.
In the end, the `GlobalConfiguration` would only be an XML / YAML loader
that returns a `Configuration` object.
