It sounds like magic. I think it would be too much to explain this 
here... But I do not like not understanding what  and how. If you have 
any hint about where I could find more information on the implementation 
( even the file in the kernel which take care of that or anything 
technical). I would be happy. If not I am already very greatful for the 
answers.

Cheer,
