I'm pretty sure we don't want to have this optimisation on for non-paged 3rd
party installation of QtWebkit. For upcoming devices this propably is very
viable option to gain performance.

1MB is massive increase in binary size. QtWebkit stands to be slighly below 3MB
that is 33%. or did you mean 1MB increase of .text segment?
Size of that in my build is ~5.8MB, still 17%.

How can you say it is a small impact ? :)

Have you tried running this on older devices, what is the impact on load times
of the DLL, how much more memory is consumed for loading? I've had issues
running debug build of webkit DLL on Nokia N95 due to device running out of
memory while trying to load the DLL. Debug size was 8MB (.text 20MB)

DLL load consumption is shared with processes, but 1MB extra impact is
critically high. "elftran -dump h <file>" will tell you how much is required to
load the DLL.

So the question boils to how much memory we will allow users to have for their
client app.
