"""
Since many Fraction input values can already be normalised for some reason, the following change shaves off almost 30% of the calls to PyNumber_InPlaceFloorDivide() in the telco benchmark during Fraction instantiation according to callgrind, thus saving 20% of the CPU instructions that go into tp_new().
"""

I then proposed to move this into the PyLong type in general, rather than letting Fraction itself do it less efficiently.
