Well, the original test is too easy with pypy...

Find all primes up to: 200000 using 64 processes.
Time elapsed: 0.62 seconds
Number of primes found 17984

How about making it a little harder and finding all primes within 1 million?

Find all primes up to: 1000000 using 64 processes.
Time elapsed: 14.71 seconds
Number of primes found 78498

But this isn't the best of benchmarks.
