> The original PriorityLinkedList implementation is based on a double linked list implementation
that suffer of:
> * fragmentation along the heap
> * pointer chasing due to the presence of nodes
> * allocation heavy (ie each add operation forces allocation of nodes)
> * high hidden (ie the nodes) memory footprint that lead to wrong memory estimations
> It is possible to provide a specialized chunked implementation that can address all these
issues while providing a better performance (throughput, latency and memory footprint wise).
