That's certainly true, but I think that Robert is willing to make that
assumption and is able to establish it, for his context.

I think that's okay for Robert, since he can override the
debug-callback to be able to tell that the execute-callback is being
run for debugging. I don't know all of the details he's dealing with,
but he's fairly agressively changing the behavior of DrScheme (in ways
I certainly didn't plan for) but they seem to be working out okay so
far.

That sounds right.

One thing I wondered: is the debug? flag still necessary?
