It does, but when unicode_decode_call_errorhandler() *doesn't* fail,
it might be called a second time later on. For performance reasons
unicode_decode_call_errorhandler() then doesn't create a new
exception object to be passed to the error handler, but reuses the
old one (the PEP explicitely allows this).

Yes, but I don't see how.
