That code was a botched attempt to match the behaviour of the C implementation. The C implementation does not expose the dispatch table unless it has been explicitly set (on the pickler or the pickler class), and it ignores any "dispatch_table" (or "persistent_id") attribute on the metaclass. I will do a fixed patch with docs.

More or less.  That code was a botched attempt to match the behaviour of the C implementation.
