It successfully combines v8 with the Ken library, giving us a crash-resilient v8. All JavaScript values are allocated in a persistent heap. Ken makes an incremental snapshot of this persistent heap after every turn of the event loop. In v8-ken, the event loop is basically the v8 read-eval-print loop. To do a little more interesting experiments, we augmented v8 with (primitive) support for processing HTTP requests as well. Obviously this is stuff that node.js handles much better, indeed, is optimized for. The logical next step is thus to repeat the v8-ken experiment, but this time combining node.js with Ken, leading to a crash-resilient node.js (this is what we call the NodeKen project). The main challenges that I see are how to combine Ken's event loop with node.js's event loop (it's no longer a simple REPL), and how to deal with socket-based communication (Ken assumes message-passing happens using discrete messaging, not using stream-based communication). The student working on v8 is no longer working at my lab. NodeKen is still on my research agenda, but I'm currently lacking the manpower to complete it. Meanwhile, I'm happy to answer questions about v8-ken, and happy to advise anyone willing to work on NodeKen.
