In his original plan, there were to be multiple instruction streams operating simultaneously. Each processor would have a few bits telling it which instruction stream to process. In the end they decided that most cases could be handled by a simple masking bit, I'm all for fine-grain parallelism so long as each grain has a grain of common sense---say around IQ 130 or so. Grains this smart have a substantial volume today, but they'll get finer. Who will make this fine grain, said the little red hen. -v
