Instead, I am just trying to publicly explore the problem space and build tools for thinking about the issues involved. I’m not sure what the “right” concurrency API is. It’s well known in certain circles that there was a sign hung up at the Mozilla office in San Francisco: “You must be this tall to write multi-threaded code”. The sign was hung about 10 feet off the ground. This little joke has an almost mythological relevance in the origin story of Rust, which was designed by a Mozilla team to make writing parallel and concurrent systems software more tractable. And indeed, Rust has well-resolved many of the problems users encounter writing multi-threaded systems. But there is a problem. Recently, Tyler Mandry wrote a
