I wrote an unrolled state machine for my async/await in Java. This models a simple async/await program and runs tasks on other threads - without locks. I use a design I call token ring parallelism, where threads take turns and are linked together in a ring structure.

I wrote a own lock free algorithm here that I use to do message passing between actor threads. My goal is high throughput performance and low latency.

With 11 threads (on a 12 core processor, deliberately left one core for Windows)

FWIW, this isn't mentioned in the book, and only extremely cursorily in the official Rust docs, but looks like 128bit atomics have landed (on supported architectures): https://github.com/rust-lang/rust/blob/19bc8fb05ab083a315ee4...
