The ones that benefit measurably a lot create *lots* of objects. Bigger apps
are more likely to allocate many objects. 

It is not a hard rule of course, specially, if you see the practice (like on
an avg Delphi forum), where people load gigantic db exports with
TStringsList.loadfromfile, eating twice the memory than the file is big,
with two allocations or so per line.
