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?

Empieza leyendo la documentación de concurrent.interpreters sobre cómo compartir objetos y el manejo existente de tuplas y mappings compartibles en el módulo. Determina cómo podría funcionar el uso compartido de frozendict cuando todas las claves y los valores sean compartibles; se considera terminado cuando los valores compatibles atraviesan intérpretes sin pickling y el comportamiento está cubierto por las pruebas pertinentes.
