Wow, nice bug. I like a lot of things about Go, but I wish they didn't invent their own mini operating system in the runtime on top of Linux/POSIX. This bug seems like a good example of why that's a leaky abstraction. I think it would be interesting to explore a coroutines + threads + channels design space for a concurrent language. Basically like Go, except without the green thread implementation. For CPU bound work, you can use threads. For I/O bound work, use coroutines. And then they all compose together with channels. The implementation would be a lot simpler because it works with the OS rather than trying to paper over it.
