 Please provide the state of all MALLINFO flags in kdebase/config.h and 
KDE_MALLOC in kdelibs/config.h, values of all struct mallinfo fields (for 
both startup and when keeping for preloading), and all the Vm* fields 
from /proc/<pid>/status.

 It is done indeed, in KonqMainWindow::setPreloadedWindow(). Maybe there's 
something missing?
