Oh, I see. The article is saying that async is required. I thought it was saying that parallelism is required. The way it's written makes it seem like there's a problem with the code sample, not that the code sample is correct.

But why is this a novel concept? The idea of starvation is well known and you don't need parallelism for it to effect you already. What does zig actually do to solve this?

Many other languages could already use async/await in a single threaded context with an extremely dumb scheduler that never switches but no one wants that.

I'm trying to understand but I need it spelled out why this is interesting.
