non-periodic function that can be easily created and checked?

Any time you squeeze a 64-bit value (address) into a 32-bit pot, you are going to get repeats.

The good thing with using the offset directly is that you know that the repeats are always going to be 4 billion bytes apart. And thus only occur if the program uses more than 4GB of heap; and on my 8GB only occur twice. (Not strictly true if I allowed my machine to go into swapping!)

With any non-periodic function, the repeats will (must) still occur, the only difference is that the spacing will vary, and be less. It could even put then in adjacent memory slots; or certainly a lot closer together.

Intuitively -- though as I observed elsewhere, there is nothing much that is intuitive about this -- the danger of the copy-over problem seems more likely the closer together they are.
