These were a feature for allowing multiple scripting contexts to access the same global state without leaking wrappers between them. For example, if the inspector wanted to modify window.Array.dangerousFunction = ... it wouldn't want the author's content to have access to that. This feature is not part of Sky's security model and thus this is just dead code. I tried to remove worlds all together, but there is something special about how we use a "fake" world (which is neither main nor isolated) for GC, regexp and testing.
