Message 260149 - Python tracker

I also ran benchmarks.  For me, django was 1% faster, telco 5% slower, and the rest were the same.  telco is a decimal benchmarks (ints aren't used there), and django/chameleon are unicode concatenation benchmarks.

I can see improvements in micro benchmarks, but even more importantly, Serhiy's patch reduces memory fragmentations.  99% of all long allocations are coming from freelist when it's there.
