I’ve worked on multi-processor systems with this attribute and I think it’s a good option, stack was private and “cheap” in terms of overhead on a processor.  If you use shared memory semantics you'll have portable code that works on multi-process (process, not processor) systems, it requires a little more design formalism up front.
