I took a cursory glance through the patch, and noticed the 'XXX' comment about looking through pickers and portals. I'd suggest looking at them as well, even if it won't be used very often. (I've moved things from pickers and portals often enough, though.) I also wonder about the 'unload' keyword. It almost sounds like something you might use to eject a tape or something. What about calling it 'return' instead? (I don't feel really strongly about this, but I figure we ought to make things intuitive, if possible.) Anyway, I'll try to give the patch a more thorough look-over in the next few days. I won't be able to do more than that before committing it, though, since I don't have a test changer anymore. (You've obviously tested it, though, so we should be okay in that department.)
