The order is unspecified, but an iteration must iterate in *some* 
order. The question (if I've understood it correctly), is whether 
that order of iteration changes when the keys aren't changed.

The spec doesn't say anything about this, although I would expect 
in practice that the order will not change.

I've added a bug to track this omission from the spec:
