ETA on multiprogramming

[JMNorris]

Just curious, but what is the eta D offering good support for multicore / 
multiprocessor / multithreaded / multiwhatever programming.  Is this 
supposed to be a D3 feature?  If so, perhaps I should expect an tea of 
about a year or two?  Or perhaps this is expected to be available with D4 
with perhaps an eta of, say, 3 to 4 years?  Please understand that I'm NOT 
expecting an answer like "Q3 2008".
