On the "why graal" page, it says that one benefit is you can use a larger heap size for nodejs applications. I would imagine one other big benefit is that you can have true multithreading since the app now runs on the jvm. Is this indeed possible? Is there any guidance on how to do it? Rhino had the concepts of Scope's and Context's to somewhat safely parallelize code, so curious if there are similar primitives in Graal?
