Instance IDs aren't currently UUIDs :) They are auto-increment
integers that are local to the zone database. And because they are
currently assigned by the zone, the work of identifying the
appropriate zone to place a requested instance in would need to be a
synchronous operation (you can't have the instance ID until you find
the zone to put it in).
