All right.  So the challenge here for windows is: if python is installed on a path that has a semicolon in one of the directory names, is it even possible to populate sys.path such that modules can be imported from the lib directory that is under that path?  (IMO we shouldn't jump through big hoops to support this, but if it can be done and the refactoring Nick is contemplating makes it *relatively* easily, it would probably be good to do, to be consistent).
