I wonder how they get the performance up so much on the first  
Parallel.For example over the multi-threaded implementation; I mean,  
internally, they must use something similar, unless they have a  
difference interface to theads running on multiple cores as opposed  
to software threads.

Note that one of the authors is Daan Leijen, who was a student of  
Erik Meijer back in his Haskell days.
