As Eli and Daniel mentioned, this area of Emacs cannot be 100% reliable


Why? Surely Emacs could switch away from recursion for the reader and the
evaluator to an explicitly-managed stack. That would be a bit of work, but
certainly not impossible.

You are right, on both points. By "this area of Emacs" I was assuming the current recursive implementation. It's not the only place Emacs recurses, though.
