Re-animating an old discussion -- Cesare, any news on the wpython front?

I did a checkout from http://wpython.googlecode.com/svn/trunk and
was able to ./configure and make successfully on my 64-bit Linux box
as well as to run the Unladen benchmarks.

Given svn co http://svn.python.org/projects/python/tags/r261 in py261
and svn co http://wpython.googlecode.com/svn/trunk in wpy,

$ python unladen-tests/perf.py -rm --benchmarks=-2to3,all py261/python
wpy/python

gives the following results:
