BTW, we have a fairly detailed design for this now, plus implementation in M5.    

I'll try to bring it up to date with the current tree, so it doesn't keep bit-rotting.

Hoping to get a write-up ready to submit to ASPLOS 2013 -- either just for use with message passing, or for accelerating a work-stealing system too (along the lines of the Stanford work from a few ASPLOS ago).
