I accidentally left out the telco benchmark, which is bad since cdecimal makes it just scream on Python 3.3 (and I verified with Python 3.2 that this is an actual speedup and not some silly screw-up like I initially had with spectral_norm):

You could also make the pickle benchmark use the C accelerator module by passing the --use_cpickle flag. The Python 3 version should be a lot faster.
