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...

The number are lower for 2.3a0. I'm closing this silly
"bug" report fixed.

I wouldn't call it "silly", and if it had been possible to
make time for it, I think it would have been valuable to
figure out why these simple operations suffered so much
across releases. I agree with closing it, though, as it's
become apparent nobody will ever have time to dig into it.
