What if bf code was really really large?

I've only been testing with the examples at hand included in my repo. The mandelbrot and towers of hanoi examples are pretty big though. If you can find some larger examples, I'd like to try them.�

I think it can be a great example. It's very educational ;-)

It could go into official docs/howto too.

Awesome! I'm working on writing up everything, it's turning out to be pretty long. I'm assuming no prior PyPy knowledge in the readers though =)

Here are a few numbers from tests I just did.

python double-interpreted: > 78m (did not finish)

pypy-c (with jit) double-interpreted: 41m 34.528s

translated interpreter no jit: 45s

translated interpreter jit: 7.5s

translated�direct to C, gcc -O0

� translate: 0.2s

� compile: 0.4s

These were all running the mandelbrot program.
