In this case, we only write using CAS (code guarantees that). We also
never update, just insert if not exist. Once a hash exists, it never
changes (it may get deleted later and that'll be a CAS delete as well).

If you ever write the same value with CAS and without CAS (different
code paths both updating the same value), you're using CAS wrong, and
inconsistencies can happen.
