Demonstration

Loading this page (http://fr.kingofsat.net/pos-13E.php) and any of this site is
MUCH longer on Windows than on Linux. When loading on Windows it takes about
7~8 seconds, takes 100%cp and freezes sometimes for a few seconds. At the
contrary on Linux it only takes 3~4 seconds. The same page loads fast on
Konqueror and Chrome but is also problematic on Aurora. Even if I try to load
this page in Widget-less application the problem is the same.
Please find attached a little demonstration : it load the page and then warn
about the time it took.

Tested with QT 4.6 and QT 4.7,  under Windows 7 Pro 64 bits, Windows Vista Home
32 bits, Windows Xp Pro 32 bits and Linux Kubuntu 9.10 64 bits

Thanks to investigate
