I just quickly and very nonscientifically poked my head into the json encoder
code from lib-python/modified-2.7 and was able to speed up the "huge" benchmark
from 700000 usecs/loop to 200000 usecs/loop, just by putting None into the
markers dictionary instead of the object itself. I'm positive that I can figure
out a few more things that pypy really, really doesn't like - but first I'll
catch some sleep.
