This is a common fallacy. Cython should still be able to squeeze another
bit of performance out of your wrapper for you. It tends to know the C-API
better than you would think, and it does things for you that you would
never do in C. It also helps in keeping your code safer and easier to maintain.

Your C code seems to be only about 1500 lines, not too late to translate
it. That should save you a couple of hundred lines and at the same time
make it work with Python 3 (which it currently doesn't, from what I see).
