Summary: python version benchmark

Initial Comment:

This is not a bug per se, but following instructions by
Tim Peters the One :), I'm submitting here the
benchmark script.

I'm getting currently the following final output
(bench.txt):

version   bench1    nogc  bench2
1.5.2        0 %
2.0         48 %    33 %    21 %
2.1.1       53 %    35 %    25 %
2.2         51 %    35 %    23 %

where:

bench1 = original python 1.5.2 script 
nogc = bench1 when disabling gc
bench2 = bench1 script 'rewritten' for python 2.0 and
latter (string methods, sre -> pre...)

These numbers are high...

Useful info from the effbot:

"""
fwiw, here's the timings I get on a slow windows box (using
PythonWare builds, and time.clock() instead of os.times()):

python 1.5: 2.01
python 2.0: 3.02
python 2.1: 3.00
python 2.2: 3.04

after playing some more, I ended up with this little 
benchmark:

def dosomething(item):
    return [None, None, None]

data = [None] * 100000

import time
t1 = time.clock();
x = map(dosomething, data)
t2 = time.clock()
print t2 - t1

python 1.5: 1.02 seconds
python 2.0: 1.95 seconds
python 2.1: 1.85 seconds
python 2.2: 1.90 seconds
