That's a significant improvement. It still decodes os.environ and sys.argv
before you have a chance to call sys.setfilesystemencoding(), but it
appears to be recoverable (with some effort; I can't find any way to re-do
the encoding without manually replacing the surrogates).

However, sys.std{in,out,err} are still created as text streams, and AFAICT
there's nothing you can do about this from within your code.

All in all, Python 3.x still has a long way to go before it will be
suitable for real-world use.
