In test_io, StatefulIncrementalDecoderTest was not part of the test suite.

And of course, the test failed:
a bytearray was used without reason in io.TextIOWrapper.tell().

The difference is that iterating over bytes (i.e. str in python2.6) returns 1-char bytes,
whereas bytearrays yield integers.
This code should still work with python3.0
