I know you want to use io_uring and you seem to think you can't. What's the issue with creating your own awaitables that use io_uring and co_await them from async's coroutines?
Actually, this would be a great test. I tried reading the docs but I'm not sure how to actually author this. So, Async runs in its own event loop. In this case, I want a separate thread with its own io_uring event loop. Something simple that basically just calls: while(true) { io_uring_wait_cqe( ... ); Unfortunately, this means I now _have_ to introduce thread synchronization latency when I'd like to use my own event loop here. Aside from that, I can write an awaitable that communicates with the io_uring context in the awaitable's `await_suspend` but I'm not sure how to get Async to know when to resume the awaiting coroutine. What would I wind up doing here? On my end, a completion queue event (CQE) comes in, I recognize it's associated with Async and now I want to tell Async to resume the awaiting coroutine, i.e. call `.resume()` on the associated `coroutine_handle`. - Christian
