1. While we're here, an _option_ to open an image read-only even when
you have write permission would be useful, for those occasions when
you want to boot from some valuable image and be certain you aren't
modifying it - without having to chmod back and forth in
Qemu-wrapper scripts, or copy the image first.
2. Would it make sense to open CD-ROM images read-only all the time,
when they are opened with media=cdrom, or can QEMU's CD-ROM devices
write to the images?
