That would be really nice indeed.

I tend to aggree with you.  As a matter of fact, doing (efficient) 
parallelism is a very hairy thing and understanding all (or just most 
of them) of its issues maybe the real problem for doing the port 
(unless one can find some direct way to translate OpenMP directives 
from Cython code to the C code, which would be wonderful).
