That's pretty neat. Thanks for pointing it out.

The abstraction on top still async based and I agree it makes sense for Zig. But in general I don't like that abstraction. I like it when it's flipped around -- the abstraction is process/thread/green thread-like and sending messages or events around. Underneath it may involved having a few IO pollers with select/epoll/io_uring, a thread pool, etc. But the top level API doesn't handle promises, futures, callback, deferreds, etc. I am thinking of Go's goroutines, BEAM VM processes, or even plain threads or processes talking over the network or locally via queue.
