I have written servers in C with epoll that were used in production, thank you. And yes, I'm aware of async/await and its limitations. State-machine-style transformations from blocking-looking code to non-blocking code are definitely helpful, but in the end still fall short in terms of usability to a full blocking style of programming. To even begin to approach the ease-of-use of blocking-style programming you need something akin to delimited continuations in your programming language.
