I guess it depends on whether you think you need the certainty of
the cleanup or not. I think both approaches are valid depending
on the context.

In this case, I asked myself that question, and I didn't see a real
need for it, since my thinking was that, if an exception occurs and
propagates through handle_inferior_event, then chances are it'll
propagate all the way, which would then lead to values being cleaned
up as well. So I went with the current pattern.

But I can change it to a cleanup if people prefer. I don't mind.
