This is the second part of the 'not crash on regionsize changes'. This lets you configure region sizes to be smaller without crashing the region. I remind you that regions are still square, must be a multiple of 4, and the Linden client doesn't like anything other then 256. If you set it bigger or smaller, the terrain doesn't load in the client, the map has issues, and god forbid you connect it to a grid that expects 256m regions.
