This forum post also seems to indicate that GC is needed for screen savers on OSX 10.6 and 10.7, but not 10.8: <http://forums.macrumors.com/archive/index.php/t-1417509.html>

This means you cannot use PyObjC to build screen savers for OSX 10.6 or 10.7, I'll update the documentation.   While it is technically possible to make PyObjC GC-safe I don't think it is worth the effort because GC is on the way out.
