Let's close this. There is no point keeping this languishing any further.

The profile and cProfile modules are different enough that we can't merge them without breaking compatibility. They should treated as two separate profilers.

Maybe in the future we should include a drop-in module written in Python for cProfile to be used for another Python implementation. But for now, I don't see the benefit, since the profile module is good enough and alternate implementations should be able to re-do the _lsprof accelerator in their target language without too much trouble if desired.
