Cross-interpreter support for efficient sharing of frozendicts

Feature or enhancement

Proposal:

The concurrent.interpreters module for subinterpreters handles sharing/sending values across interpreters with direct sharing of some basic immutable types, and a fallback to pickling others. As an immutable container, tuples are supported (as long as all items are themselves shareable). Similarly, I think it would be good to support sharing frozendict without serialization (if keys & values are shareable).

Because dictionaries are so fundamental and common, having a better and more performant way to share such a mapping would significantly improve the experience of using concurrent.interpreters and InterpreterPoolExecutor.

Has this already been discussed elsewhere?

Comece lendo a documentação de concurrent.interpreters sobre o compartilhamento de objetos e o tratamento existente de tuplas e mappings compartilháveis no módulo. Determine como o compartilhamento de frozendict poderia funcionar quando todas as chaves e valores forem compartilháveis; considera-se concluído quando os valores compatíveis atravessarem interpretadores sem pickling e o comportamento estiver coberto pelos testes relevantes.
