I've just read the paper and they look both useful and interesting to
implement. Adam mentioned that GHC would need to be extended first,
and I can't really judge how much work that would be. Can anyone chime
in on how feasible that is?

The data structures I mentioned were just my initial ideas, I'm open
to any other suggestions. In my (limited) experience with parallel
programming, queues and priority queues tend to come up quite a bit,
but I'd be happy to get input from anyone with more experience
regarding what would be useful/important.
