The reason why it fixes things is that there are many file-system
operations that plain fail when that path being moved, for example, has
something else bind-mounted to it. 

To the best of my knowledge, the consequence in this case is that some
program is trying to write to /home/olpc/.Xauthority and failing because
of the bind-mount. This causes X to reject Sugar's connection attempts
(hence the AUDIT messages) and results in an infinite
init-restarts-X-which-dies loop.
