At this point, multiple use cases beyond the specific ptxas verification use case that started this thread are arising, so it sounds like a new construct that's general enough to handle them all is warranted.  For that general case, I agree with your arguments along the above lines.  Thanks for explaining your position.

Thanks.  I wasn't aware of that use case.
