Just wait a bit longer.  This is an extreme case of long arithmetic, where
CPython has (I believe) a special implementation for "x * x" where x is a large
object of type "long", which we are missing.  It's in other words completely
unrelated to multiprocessing.  If I tweak the example until it looks more like a
real load (see test2.py), the numbers are in favour of PyPy again.
