New submission from Ethan Furman:
enum34, the Enum backport, specifically uses `protocol=HIGHEST_PROTOCOL`, while
the current enum tests just use the default.
Running the enum34 test expose an issue with pickle protocol 4:
======================================================================
ERROR: test_subclasses_with_getnewargs (__main__.TestEnum)

Traceback (most recent call last):
