diff Lib/test/test_bytes.py @ 41425:0486deaaade3
An example of action-at-a-distance: fix the problems I had in test_io.py
without touching io.py or test_io.py. The cause of the failure was that
bytes objects didn't pickle right. As a stop-gap measure, I'm providing
bytes pickling via copy_reg. Eventually, we should use a more efficient
protocol, e.g. __reduce_ex__ or __getstate__/__setstate__.
