I think the idea of what multi-threading will bring is getting a bit
carried away. I fully expect it to be limited to RSI-controlled code,
and not configureable by the user. I.e., I don't suspect you'll be able
to craft your own thread-aware routines, but rather rely on the internal
multi-threading of certain built-in routines for increased speed.
Someone please correct me if I'm wrong.
