Well, another possible memory optimization is to merge
SwSortedObjsImpl into SwSortedObjs. What is the reason to use the
"pImpl" pattern here?

Ok, there are many SwFrms in a big doc... We don't want to throw away
memory. But we would use a shared between the SwFrm instances static
variable for an empty list ("null object"), and return it in
GetDrawObjects when our SwSortedObjs is dead. What do you think about
it?
Kind Regards,
