You might also search in rtl/ (especially objpas), because that contains 
the core of FPC's class system (and almost everything passes through 
that code some time).

You might also try a proof of concept implementation of your idea to 
demonstrate whether there really is a benefit (you can replace the 
default memory manager, so you should be able to test this without 
touching the current default heap manager).
