for loading modules from the application resource fork stopped working
when sys.path component normalization was implemented. Comparison
of sys.path components is now done by FSSpec in stead of by pathname.
There's also new support for importing code fragments: if a file on
sys.path contains a PYD resource with resourcename equal to the name
of the module to be imported this PYD resource should contain a
(pascal) string with the name of a code fragment to load. This allows
freezing Python programs without access to source or a development
environment.
