I find it hard to reproduce.  For example, I modified euler24.py to call 500'000
times the function solve(), and it takes 11.3 seconds on CPython 2.7 versus 1.91
seconds on PyPy 2.0.2.  Running the same function with "timeit -n 10 -r 3"
doesn't make any sense at all, because it takes no measurable time.
