I would call that code THE example of where an inlining, tracing JIT
doesn't work.  It's recursive, with a dozen unpredictable places where
the recursion can occur.  Unless the heuristics are good enough to
stop *all* inlinings of this function inside itself, then we just get
an explosion of traced paths, right?
