Wouldn't it be nicer to have a facility that let you send messages between processes and manage concurrency properly instead? You'll need most of this anyway to do multithreading sanely, and the benefit to the multiple process model is that you can scale to multiple machines, not just processors. For brokering data between processes on the same machine, you can use mapped memory if you can't afford to copy it around, which gives you basically all the benefits of threads with fewer pitfalls.

I don't think this is an answered problem. There are plenty of researchers on both sides of this fence. It is not been proven at all that threads are a bad model.
