[Haskell] par and forkIO

Essentially not at present; but it's high on our list.  Because of the
fun we've been having with Software Transactional Memory (STM), which
will be in GHC 6.4, and because of the multi-core machines that are
coming right now, Simon and I are starting to think much more about
genuine hardware concurrency, esp on multi-cores.  We have not actually
done anything yet, but I think we will soon.

STM is described in a PPoPP paper on my home page

| Multicore and multi-cpu machines are getting more and more common.

| Do the current implementations of par and forkIO in e.g. GHC take
| advantage multiple CPUs/cores or is special plumbing needed (GPH?)?
