The advantage of separate `DoResume()` and `DoResumeReverse()` methods is that `Process` subclasses that don't support reverse execution don't have to change at all; they inherit the default `DoResumeReverse()` that returns an error. If I make `DoResume()` take a direction parameter then those implementations (three out of four AFAICT) need to add a check of the direction parameter. It's not a big deal, I'll change it.
