Part of it will be that Python 2 has 2 integer types: 'int' (fixed
length) and 'long' (variable length).
Originally, 'int' addition could overflow, but it was more friendly to
promote the result to 'long' instead.
That was my first thought on reading the thread and was going to post
that as the reason for 3 being a little more sluggish.
But then I tested Python 2 (2.7.11), and I couldn't get integer
arithmetic to overflow at all!
