I think, and I've mentioned before, that we should gradually try to
remove this assumption. There are some use cases for having multiple
InteractiveShell objects in one process. It's one reason I like the
extension system - it achieves loose coupling without assuming that
there will only ever be one shell object.

This is a low priority, long term goal, though.
