---------------------------------
    Resolution: Rejected


Rejecting this as the hashCode is a lot more beneficial than originally thought.

> We could remove the hashCode 4 bytes taking up space in the allocated memory block. Currently this is only used for eviction, maybe instead we could write a VInt that says which offset of locks to use. In majority of cases <= 64 cores this will result in saving 3 bytes per entry.
