Use default pickle protocol for hashing
Use default pickle protocol for hashing

Because the pickle protcol is part of the pickle, this ensures that the
same object can not hash to the same value in Python 2 and Python
3. Having the same hash in Python 2 and Python 3 could cause problems
when you cache the result with a Python version and try to load it under
another Python version.
