I seriously doubt any controller in his right mind would turn two perpendically crossing aircraft in different directions to delay the cross unless one is supposed change level. That would put them parallelish so when and how are you going to resume them without changing level???
I think ferris is quite right, maybe a bit too harsh. How many of you actually bothered looking at what cauatc is suggesting and claiming he is a controller?
Either way caucatc, turning them left and right simply delays the cross but does not solve the problem. By turning them the same way, you push the one behind further behind and one in front further front. Draw it on a paper and you will understand.
ATC maybe handled different in different countries, but you cannot change the basic rules of physics.
