SMC shouldn't need writeback unless it needs those buffers to be maintained, though, right?

Do you modify any of the data buffers you put in the program? That counts as "SMC" as far as the fact that you're modifying things within the program space.

No I don't. And I can prove it with the fact that zStart doesn't perform any writeback on my programs.

True, but there's no way to communicate that back to the shell.

You still can restore their initial state. For example, if every byte was at 0 at the beginning, you set them all back to 0 before leaving
