Consider Concurrent Smalltalk on the http://cva.stanford.edu/projects/j-machine/ http://cva.stanford.edu/projects/j-machine/ -- a processor-in-memory massively parallel architecture. This seems like a better match to physics than a Von Neumann architecture with a few fast processors separated from a giant memory, because physics is local. I suspect systems like the J-machine haven't gotten very far for historical path-dependent reasons more than intrinsic ones. It's true though that a parallel object language like Concurrent Smalltalk isn't the historical Smalltalk we usually mean.
