I'm still not understanding why you think this means "object reuse" applies here; my understanding was that "object reuse" applied to reusable read/write storage like disks & memory -- if user A frees a page, and the system recycles it and gives it to user B, user B better not find any of user A's data in the page. the "removable stuff" in a typical scanner is not writable by the scanner. ("all in one" devices with both scanner and printer typically have separate paper paths for print vs. scan). There is nothing SOFTWARE can do about people who left something on the scanner bed when they logged out and wandered off. What's more, the software being proposed here does not need special privileges to operate; if some sort of device allocation/object reuse controls need to happen, they would need to happen in trusted privileged code at device open time. - Bill
