Ok, I'll broach the question: What would it take to get coroutines into JDK7? Is it too late? Does it just need someone to lead a JSR?
Of all the features in Ruby 1.8.7 and 1.9, the one that scares me the most is inbuilt coroutine support. We've so far managed to simulate them ok with threads, but as Lucas's post showed, we fall way behind on message-passing performance. And this says nothing about the cost of spinning up full native threads for short-lived coroutines while trying to guarantee their lifecycles don't root objects longer than they should. So, what's the situation? - Charlie _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
