Yes, it's always good to double-check the autogenerated C code that
Pyrex makes. (This becomes especially important if you release the GIL
from your Pyrex code -- I once spent days tracking a weird race
condition in threaded code due to this simple oversight.)
I'm glad Pyrex is working to get comparable speeds to pure C now.
