Armin Rigo:

To save memory, it would be useful to figure out some operations that generally give an integer that fits in a machine word, even if the operation involves large integers.  The most obvious example is ``long % int``.  On PyPy2 this must always give a ``long``, but there is no such condition on PyPy3.
