 * An MPSC array queue which starts at <i>initialCapacity</i> and grows indefinitely in linked chunks of the initial size.
 * The queue grows only when the current chunk is full and elements are not copied on
 * resize, instead a link to the new chunk is stored in the old chunk for the consumer to follow.
