It seems reasonable to me.  I think the advantage it has over my
approach is that the resulting classes are more similar to what we would
have written had we implemented a custom class to replace each cleanup.
Also it helps enforce the idea that we don't want cleanup_functions to
be used in an unrestricted way.

Yes, let's do this.
