This is the fetching of leases from the school server once they have
expired (or for the cases when there is no activation at all, e.g.
right after reflash). Thats the first way that laptops can receive
leases. This codepath does not execute at other times. And it only
works when you're in-school.

The other way that they receive leases is through the
olpc-update-query cronjob which basically ends up with
olpc-update-query querying the internet-based paraguayeduca mothership
once per day. This server will deliver updated leases to the XO
laptops *before* they expire, which has a few advantages. (for
example, there was one time when Raul realised that the current round
of leases were set to expire in the middle of a long school holiday.
this system was used to deliver much-extended leases in the final week
of school before the holidays set in).
