Roshan James was working on parallel GC at MSR Cambridge last year.
Unfortunately, it's not an internship-sized project.

I think that the need for it will become more pressing among GHC's
developers as the NPH work matures, as the current GC reduces
performance even on two CPUs. The need to publish good numbers is
always a helpful motivator :-)
