Docs Are Not Clear on How to Share a Queue Between Interpreters

Documentation

Users create cross-interpreter queues by calling concurrent.interpreters.create_queue(). @terryjreedy pointed out that the docs aren't clear about how to get a queue in one interpreter over to another interpreter. See https://github.com/python/cpython/issues/139383#issuecomment-3354723401.

The docs entry for concurrent.interpreters.create_queue() should call this case out specifically and include a short example code snippet. It would probably be smart to add something similar to the docs entry for Interpreter.prepare_main(); the original motivation for that method was to pass a queue to another interpreter.

找到 concurrent.interpreters.create_queue() 和 Interpreter.prepare_main() 的文档条目，然后查看 issue 139383 中链接的讨论。添加清晰的说明和简短示例，展示如何在解释器之间传递队列，并为 Interpreter.prepare_main() 提供类似的指导；当两个条目都明确记录这一用例时，即视为完成。
