Fine-grained concurrency for Ruby

Project mention: Should You Be Scared of Unix Signals? | news.ycombinator.com | 2023-10-16

When using green threads/fibers/coroutines, an interesting technique to make signal handling safer is to run the signal handler asynchronously on a separate fiber/green thread. That way most of the problems of dealing with signals go away, and there's basically no limitation on what you can do inside the signal handler.
I've successfully used this technique in Polyphony [1], a fiber-based Ruby gem for writing concurrent programs. When a signal occurs, Polyphony creates a special-purpose fiber that runs the signal handling code. The fiber is put at the head of the run queue, and is resumed once the currently executed fiber yields control.
