N = 200 means most of the benchmarks probably won't even JIT, so that
might be a start.  The threshold in the released pypy is N = 1000.

But even without JIT, 20+ fold slowdowns are very interesting:
10n_render, query_all and query_raw.

I wonder if anyone has benchmarked sqlite under pypy - that would have
the most dramatic effect here.
