Forget the separate memory spaces. That's not the issue. The reason for wanting to share memory between threads within the same process is to simplify inter-thread communication. I'd like to prevent other applications from screwing with memory belonging to my app, but still allow free (but mutex protected) sharing of data between threads within my application. This doesn't require separate memory spaces as Amiga OS is a single memory space OS. It would require a concept of child-tasks (and possibly a new memory protection classification).
