Biggest chunk queue is the same as a page queue

The biggest chunk queue could use the same implementation as the corresponding page queue, as each chunk only holds one page.
The page based implementation is orders or magnitude faster, so that would be a great start.

Furthermore, the biggest page queue could also reuse its pages aka chunks, as one page is already a chunk.
Maybe we could add a custom queue for this, which is a mixture between a page-based and a chunk-based queue.
