[Python-Dev] Profiling of generators broken

[Neil Schemenauer]

Here's a simple test:

    from __future__ import generators

    def test():
        yield 1
        yield 2

    import profile
    profile.run("list(test())")

It looks like the profile module is getting confused by functions that
get called once but return multiple times.  My proposed solution is to
modify ceval.c so that call_trace(..., PyTrace_CALL, ...) is called
when a generator is resumed rather then when it is created.  Sound
reasonable?
