Note: bcc python-dev,cc: python-3000
"broken" systems will always exist. Code to deal with them must be
possible to write in python 3.0.
since any given path (not just fs) can have its own encoding it makes
the most sense to me to let the OS deal with the errors and not try to
enforce bytes vs string encoding type at the python lib. level.
