It looks promising. I'm not sure if Parrot needs it, though. The DOD phase is relatively low latency (as compared to, eg. Sun Java). But parrot hasn't seen the likes of big, memory hungry projects yet. I say it's worth looking into, and if not now, keeping it in mind if we do run into problems. Luke
