Sorry, I don't get your point.  Sure, Windows makes process creation
hideously expensive and has no forking.  But all kinds of BSD, including
MacOSX, are just great at forking.  Why is a preference for multiple
processes over threads "forgetting about BSD, MacOSX", or any other
flavour of Unix for that matter?

Again, I don't get it.  Why would multicore CPUs be any worse than
current multi-CPU machines at multiple processes, and forking?
