So, the problem here seems simply to be that we blow up the stack by
recursing so ridiculously deep? I think?
Looking at mark_object, it seems like it could pretty easily be
rewritten to be non-recursive, just by changing it into a loop, and
using a stack to do visit all the objects.
But that's probably not an Emacs 24.1 thing.
The other question is what other interesting deep-nesting bugs a
structure like that might reveal, so even if we fix the mark_object
case, that might not help us much. Difficult to say...
