This whole discussion regarding concurrency/parallelism stacks made me think that there's probably a good blog post to write: Start with low-level OS system calls and show what pieces one needs to write to reach higher level abstractions like futures, coroutines , async / await, nodejs style event loop, or full blown actors. That would also make for a nice roadmap to whoever would like to build OTP or Akka style framework in Rust.
