Ken McLeod recently responded to my original query (no, I'm not going to quote
two pages.)

Unfortunately, he erred in exactly the opposite direction that I did. I first
said, "I'm using an ActionProc, and its arguments are sometimes garbage." Ken
responds "Declare you arguments explicitly." That's exactly what I was doing,
and that's why I was crashing.

In fact, ActionProcs take EITHER two args (normal case) or none, for "dial
indicators." That's one ugly interface. Yuck. (Wonder how NeXT does it ;-)
