This is the type of thing I had in mind. What I was wondering was whether,
since "interrupt handlers are not reentrant" (someone - Ralph Swick, maybe?)
speaking at the recent MIT X11 seminar), is this a safe thing to do? In other
words, am I confusing two issues here? All of this assumes, of course, that
I write my code perfectly... (lest the Softies bust me).
