After thinking about this some more, are you absolutely sure that the
memory usage of the PageItem classes themselves in contrast to the
temporary image buffers PageItem::m_image or the memory usage of the
SplashOutputDev used by the poppler-qt4 frontend is the actual problem?

(One user reported that certain documents drive the SplashOutputDev to
consume several hundred megabytes of memory leading to enormous memory
consumption of both qpdfview and Okular whereas Evince was fine since it
uses the CairoOutputDev...)

You should be able to find this out if you replace lines 807 to 817 in pageitem.cpp by something like
"image = QImage(1, 1, QImage::Format_ARGB32); image.fill(Qt::white);" in a current version qpdfview's trunk to suppress rendering.
