The pybench results match those of timeit.py on my test machine
in both cases. I just mixed up the headers when I wrote the email.
Here's the console print-out:

Calls.py is using timit.py against the PythonFunctionCalls
test and Exceptions.py the TryRaiseExcept test.
Function calls are slower in 2.5, while try-except in 2.5 is
faster than 2.4.
I've attached the Calls.py file below.
