I'm not quite sure I understand the function above, are you basically
doing this?

M-: (recursive-edit)
M-: (error)

And you say that this returns you to the to the top level?

It doesn't do that for me -- unless I have debug-on-error set, and use
`q' to exit that (which returns to top level, as advertised).

Is this what you're seeing?
