Other reservations:

- why aren't the linked list pointers not included in the hash entries?
  that should simplify some logic quite a bit

- is it useful to keep the shared / split keys mechanism? shared keys
  are mostly useful for instance dicts

- does it have to inherit from dict? that looks like a potential can of
  worms
