     Several unrelated gnarly bugs later I finally got around to finish the patch to add a mount beneath the top mount. Sent it last week. IOW, allowing to atomically update mounts.

     As usual all the fun was in mount propagation. It's currently called "MOVE_MOUNT_TUCK" but I'll rename to "MOVE_MOUNT_BENEATH".
