the results you just posted appear to show a 20% slowdown for function 
calls, and a 10% speedup for exceptions.
both things were optimized at the sprint, and the improvements were 
confirmed on several machines. on my machine, using timeit on the test 
bodies, I get noticeable speedups for both tests; from my earlier post:
function calls:
> 25 usec per loop for Python 2.4.3
> 22.5 usec per loop for Python 2.5 trunk

try/except:
> 15.1 usec per loop for Python 2.4.3
> 23.5 usec per loop for Python 2.5 alpha 2
> 11.6 usec per loop for Python 2.5 trunk

maybe the function call issue is an AMD64 thing? or a compiler thing? 
do you see the same result on other hardware?
