oprofile already has an interface to let JITs export
information about the JITed code. C Python is not a JIT,
but presumably one of the python JITs could do it.

http://oprofile.sourceforge.net/doc/devel/index.html

I know it's not envogue anymore and you won't be a approved
cool kid if you do, but you could just use oprofile?

Ok presumably one would need to do a python interface for this
first. I believe it's currently only implemented for Java and
Mono. I presume it might work today with IronPython on Mono.

IMHO it doesn't make sense to invent another interface for this,
although I'm sure someone will propose just that.
