* [3.9] Improve asyncio-dev 'Concurrency and Multithreading' docs (GH-20882) ↵Miss Islington (bot)2020-09-041-0/+10
| | | | | | | | | | | | | (GH-22009) I added some information to the `Concurrency and Multithreading` section of the `Developing with asyncio` guide. This is all information that would have helped me when I started using asyncio. I incorrectly assumed that `loop.call_soon_threadsafe()` and `run_coroutine_threadsafe()` could be called from a thread in a process separate from the one that the event loop is running in. Explicitly stating that this will not work will probably help some people starting out with asyncio in the future. I also added references to some other functions that can be used for inter-process communication without blocking the event loop. The section already mentions running blocking code in a ThreadPoolExecutor, but I think listing these other options in this section will also be helpful.
