State of parallel GC?

I seem to recall reading in a GHC status report that there was some
work going on with parallel garbage-collection. Looking at 6.8.1, it
seems pretty clear that it didn't make it. Is there any update about
where things are on that front?

It isn't an immediately pressing need a Bluespec, but we do get asked
every once in a while about parallelizing the Bluespec compiler. One
of the technical reasons we're holding off on that front is that it
wouldn't win as much as people expect (because garbage collection is
usually a decent fraction of a typical run), so we'd be interested if
the state-of-play in that area changed.
