I'm going to go write some test programs and send them to you sometime a bit later today. I must admit this is a fairly baffling bug -- the next area of exploration is probably into how the various forms of uid (effective, saved, real, ...) are set up by xterm. It's odd that the problem persisted once the setuid bit was removed from xterm, in particular. I should get back to you sometime later today. Thanks!
