the biggest chunk you would see in performance would be by changing the
QueueImpl's collection.
There are a few requirements we need to meet on that collection. starting
from converting PriorityLinkedListTest to work with the same semantics on
ChunkedQueue.
I don't see an implementation for Iterator at your Queue though.---
