* Make a better job of preloading Python, especially when it's in a framework. Go for the Python file in the frameworks directory in preference to any libpythonX.Y.dylib. Particularly, don't try to preload any library without an absolute path until we've exhausted all our framework possibilities (so as to avoid picking up an ancient system library).
