A classic solution, but - unfortunately - applied to a (not even very
big) real world Org-mode parse-tree the debugger is entered immediately
(without showing a backtrace really). I think recursion becomes to deep
and max number of allowed symbols is exceeded rapidly.

Although this asks for a recursive solution, I would need one that works
on really big sexp's (like parse-trees of moderate to big .org files). 

Is that possible, or do I de facto need some kind of iterative solution
here for the real world?
