How do you know? it doesn't seem to be the case. I tried to load a
2MB file both ways and the memory consumption seemed to be the same
(plus or minus a few KB).
I tried then to load a 72MB file and the memory consuption was
77,532KB with the do{} and 77,452KB without. Not sure why the
difference, but it's definitely not twice more.
Unless of course I overlooked something.
