OK, let me gently disagree about this :-). In terms of code complexity, adding a call to `Process::CanReverseContinue()` is a tiny bit more complex than not having it. In terms of performance, I don't think it's important to make it a tiny bit faster to report that reverse-continue is not supported. Is there some other consideration?
