.org that is :-)

Could you run a benchmark before and after this patch?  I'd like to
know speed diff. Something like:

./python.exe -mtimeit 'def foo(*args): pass' 'foo()'
./python.exe -mtimeit 'def foo(*args): pass' 'foo(1)'
./python.exe -mtimeit 'def foo(*args): pass' 'foo(1, 2)'
./python.exe -mtimeit 'def foo(*args): pass' 'foo(1, 2, 3)'
./python.exe -mtimeit 'def foo(*args): pass' 'foo(*range(10))'

You can post the speeds in the patch.
