[Python-Dev] Pie-thon benchmark code ready

Dan reported a problem with the benchmark on Mac OS X:

After some off-line email exchanges I think I have a fix for this
behavior, which must have to do with a different length of the
addresses shown in the default repr(), e.g. "<Foo object at 0xffff>".

Version 1.0.1 of the benchmark is at the same place as before:

  ftp://python.org/pub/python/parrotbench/parrotbench.tgz

(You can tell whether you have the fixed version by looking at first
line of README.txt; if it says "Parrot benchmark 1.0.1" you do.)

I haven't heard back from Dan, but I assume that the fix works.

Happy New Year everyone!
