New submission from mikefc <coolbutuseless at gmail.com>:

My timings with a recentish pypy nightly and cpython 2.7.4:

Interpreter | Queue Implementation | time
------------|----------------------|---------
pypy        | python               |  1.372s
pypy        | cpp                  |  5.027s
cpython     | python               | 18.046s
cpython     | cpp                  | 35.330s


So calling into the cpp implementation with CFFI is a ~4x penalty for pypy and about a 
~2x penalty for cpython.
