ok, so probably C functions are somehow 'transparent' to the profiler which does not report them,
but reports the python functions called by the C one...

strange, what I get now is:

and in fact if I look at nc.__dict__ there is no 'astype' key. I'm running the whole program (rather
than just the function) under ipython, starting it with

> %run -d myprog.py

maybe this could mess up things?
