Not currently. It's not clear what a "point" in execution *is*! The top-level IO monad thread might provide such a point, but even then it might not be clear how much of a lazy data structure had been evaluated by that "point". I could see sense in having an I/O operation markProfile :: String -> IO () which would put a labelled vertical line on the profile to say when that "point" was.
