I skimmed the paper for stuff relevant for general-purpose programming, 
and it's even better than I'd hoped.  Erlang will be perfect for this 
new architecture, and this dovetails reasonably well with our goal of 
building on a message-passing model for Tango as well.  The integration 
with TBB and OpenMP is a nice touch too.  I suppose that means we really 
need support for at least the scheduling aspects of these in a D library 
as well.  Hm...
