OGR_GEOJSON_MAX_OBJ_SIZE is not a limit on the file size, but on the 
maximum memory allocation for a single GeoJSON feature which is 
estimated before the feature is read. As country borders are usually a 
single GeoJSON feature, a country with a complex coastline is the 
typical case where you need larger features.
