Array.prototype.join with cycles

Given the following:
var x = [1,2,3];
What should happen? The behavior demonstrated by V8, Spidermonkey, and
Chakra (haven't tested others) is to return the empty string for cycles,
thus returning the result '1,2,3,'. However, unless I'm missing something,
this behavior is unspecified and an equally valid result would be to
infinitely loop or throw a recursion error.
For comparison, JSON.stringify explicitly specifies how to handle recursion.
