In cases where MzScheme is many times as fast as Python, that's the
JIT.

Where MzScheme is a little faster or a little slower, the recent
improvements have nothing to do with the JIT. Those benchmarks are
about effective libraries and effective use of libraries, and
improvements were mostly a matter of revising the benchmarked code.
