Well, these are some warnings about not checking that the output was properly set. From my view, these are not new to this patch, it is just the pattern we see, which is fire-and-forget writes to stdout, which seems quite reasonable. If we decide to fix this, it would make more sense to do it file-wide instead of just in this patch code.
