[Giampaolo Rodola']

New submission from Giampaolo Rodola' <g.rodola at gmail.com>:

A patch including tests is in attachment.
Example usage:

>>> from cProfile import profile
>>>
>>> @profile
... def factorial(n):
...     n = abs(int(n))
...     if n < 1: 
...             n = 1
...     x = 1
...     for i in range(1, n+1):
...             x = i * x
...     return x
... 
>>>
>>> factorial(5)

Before including doc changes I'd like to hear whether this is actually desirable or not.
