OK, so I have to be more careful in the way I phrase things.  Let's say that performance isn't going to be the most significant criterion and that it would take intent to "preclude" efficient operation on any architecture, specially when one might be speculating about the architecture in the first place.

Plan 9 and NetBSD are sufficient examples that portable design is unlikely to be intentionally inefficient.
