Cython bootstraps the tiny truely performance-critical part of it 
(Scanners.py) into C code during installation and uses an external 
Scanners.pxd file to override the Python types in the module with C types. 
The other modules don't seem to matter in benchmarks, but compiling the 
inner loop of the scanner clearly gives a performance boost.
