Thanks for this article and to ingve for submitting it. Concurrency and async is my favourite topic. I think event loop programming is very interesting, and Goroutines mean every process is effectively an event loop. So I like server programming. I have an epoll server that multiplexes multiple sockets per thread which is a bit more scalable than a thread per socket. I like nodejs libuv, but I think we can go further. I wrote a very simple toy lightweight 1:M:N (1 scheduler:M kernel threads:N lightweight threads) thread scheduler in C, Rust and Java. https://github.com/samsquire/preemptible-thread https://github.com/samsquire/preemptible-thread It works on the principle that hot loops can be interrupted BY ANOTHER THREAD (the scheduler thread) on a timer by setting a loop to its limit, to give lightweight threads a chance to execute. What I think I want today though is an extremely rich process/concurrency API that resembles a stream API but for processes. For example, we should be able to create pipelines that can be paused, resumed, forked, merged, drop_while, iterate_until and whatever else would be useful.
