> Two good suggestions:
> 1. Use a probing scheme to increase density without increasing the collision
> rate
> 2. Only count unique updates to the offset map (i.e. if the key is all zero,
> don't count it) when computing the load. Dynamically choose the end offset
> based on when the map is full.
> Would be good to investigate these things.
