* 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).
