except that the ordering stays the same provided the hash does not change
I wouldn't even rely on this. The current implementation does it this way, but there's no telling what could happen in the future. Hashes have no order whatsoever, and you shouldn't rely on the any side effects to get an order.

I could see perl going to some type of lazy, hash rebalancing structure. In this model, when cpu usage is low, it reoptimizes the hash. If this were the case, then the order might change, even though you do alter any elements in the hash.
