Since that article was penned, the northern complex runways have become available for A380 operations, which significantly reduce the disruptions to ground ops. The article is also a little over the top by saying that it brings all ground traffic to a stop, when in fact it just restricts the use of the adjacent parralell runway or taxiway. A 'rolling blockade' follows the aircraft around the tarmac. It is an additional restriction to ground ops, but not that bad.
