The purpose of re-enabling this function was to provide a means to
restart Sugar if it became unresponsive, without having to wait for a
full reboot. This is useful in a classroom setting because children
always find new and interesting ways to mess things up :)

The implemented solution would need to work even if Sugar appears to
be locked up.

The ideal solution would be for the OS to manage resources so as to
minimise the likelihood of lock-ups occurring, but that is a separate
debate.
