"aren't very good names" is not really an argument I can work with. Why not? What if you want to attach/detach to events but not be persistent. Which also begs the question how long are we persistent? The whole system runtime or until the user decides to detach. So ATTACH/DETACH in the sense of attaching processes to events for an arbitrary amount of time *and* *not* for the duration of the tracee as we do it currently implicitly, is much more generic wrt usage than specifying that specific persistent case.
