Under what circumstances are linked lists useful?
...llocations on inserts/deletes.
Initial loading of the hash table is pretty fast, because the array is filled sequentially (plays very nice with CPU cache).
Not to mention that a chaining hash table is expensive in terms of memory - and this "trick" cuts "pointer sizes" in half on x64.
