[Cython] Measuring "C-ness"?

[Magnus Lie Hetland]

I'm writing a system where I build data structures for searching using  
a blend of Cython and Python code. Ideally, though, the search  
operations (performed after the structures have been built) should be  
initiated from Python, but then stay in as pure C as possible (to keep  
the Python/Cython overhead to an absolute minimum).

Now, I could (and probably will) inspect the code to determine this  
"manually", but I was thinking -- perhaps I can automate it somehow?  
At least partially? And I thought I'd ask if you might have any ideas  
in that respect.

In other words, I'd like to profile the code, to see where it goes  
through Cython/the Python C API (or even Python code), so I can  
eliminate those calls. Could I just use a standard profiler here,  
perhaps? (I'm guessing all C stuff will then just be black-box  
references, but that's OK, I guess.) Any other ideas? Some global  
location where I could insert a counter into the generated code? Some  
existing Cython magic?
