Revision history for Data-DDSketch-Shared

          - Frozen read-only mode: freeze() seals a file-backed structure;
            new_readonly() maps it O_RDONLY and queries it lock-free.
          - Create leaves the backing file sparse.
          - Recover a file left behind by an interrupted create instead of
            leaving the path unopenable.
          - unlink() reports a removal that failed; one already gone is not an
            error.
          - Hardening: re-entrancy with tied and overloaded arguments, and
            DESTROY on an invocant that is not one of ours.
          - Documentation and test-harness corrections.
