   That's a good point. It's unclear to me what the performance impact would be if we don't allow multiple copies of random states in case one doesn't care about reproducibility. Also, I'm not sure whether waitall resolves the race condition completely in the case where multi-threaded execution happens and we use the thread-safe cached op.
