At this time, there really aren't any such tools. The Cython folks
have plans to do something like this, though. Now that they can fake
frames, it actually shouldn't be too hard for them to insert the
appropriate tracing calls. We would just need to figure out how to
tell line_profiler which functions it should be profiling. Currently,
I use the kernprof.py script, which provides the @profile decorator,
which extracts the code object from the function and keys off of that.
