The first linked article was recently discussed here: RIP pthread_cancel (https://news.ycombinator.com/item?id=45233713)

In that discussion, most of the same points as in this article were already discussed, specifically some async DNS alternatives.

See also here the discussion: https://github.com/crystal-lang/crystal/issues/13619

Just curious how you approached performance bottlenecks — anything surprising you discovered while testing?

It's weird to me that event-based DNS using epoll or similar doesn't have a battle-tested implementation. I know it's harder to do in C than in Rust but I'm pretty sure that's what Hickory does internally.

This article [0] looks at similar problems. It seems like something as fundamental to the Internet as DNS APIs should be a solved problem by now, but maybe being so fundamental makes it hard to change things.
