Great reference.  Thanks!  

Another neat thing to come out of the depths of Harlequin.  I guess
the question is how well it works and how easily it can be integrated
into a project that isn't Lisp or ML.  

I see it uses a 5 phase collection to support coordinating pools,
rather than the 2 or 3 phase collection typical for an integrated
heap.  I have to wonder what kind of overhead that imposes.  I also
see they like read barriers rather than write barriers.

Have to investigate it some more, but just offhand it looks like a
wonderful toolkit.  Certainly a great help for experimentation.
