If it's implementation dependent then I see no reason for it to be in IO (this was mentioned on another ML). On the other hand, something that changes run-to-run strikes me as good to keep in IO, otherwise I'd be too tempted to serialize & save it for some purpose and get confused while a later read was corrupt.
