CloneOpenedToplevels, which is never called, is the only interesting caller of CloneToplevel. And CloneToplevel, in turn, is the only interesting caller of CloneManagees. Which means we can ditch all this code for a decent amount of space savings, both in code and writable static data (no more useless virtual function entries in vtables).
