I will add a comment to prevent new callers using this inappropriately. qemu-img/qemu-io do not use image streaming so we never hit an abort(3). But I still have an interest in solving the larger problem because QED broken in qemu-tools! So I'll look into using the main loop in qemu-io/qemu-img based on Paolo's patches independently of this image streaming series. Stefan
