Hi Dinu,

just run nightly

http://buildbot.pypy.org/nightly/trunk/

ideally, also don't benchmark on OS X, it's a system that has lots of
strange problems.

For what is worth, you picked up a very terrible program - this
program exercises long implementation, not "how fast you run python
programs". A new pypy is ~30% slower than cpython, which we find
reasonable (because it's runtime time), if you want faster pick gmpy.
GMP however has no means of recovering from a MemoryError.

How do you want to benchmark python compilers on this? Can anyone do
something more sensible than just call operations on longs?

Cheers,
