If you discard the old array (and allocate a bigger one before), you must also copy all enqueued material.

Also this one enqueue will be mega expensive - a clear "fat tail" in the latency histogram.

In MultiArrayQueue you keep all already enqueued material in-place, "just" allocate the bigger array, register the new diversion, enqueue the one new element - and done.

Thanks
