The hare/tortoise method we use in data.c?
Yes, that's a good suggestion, as Brent's teleporting tortoise-hare algorithm (see citation in lisp.h) is quite good at lessening the overhead of checking for this rare situation. Perhaps there's a way we could "export" that algorithm from the C code, so that Elisp code could use the algorithm without having to reinvent it.
