It only loads the resources as you use them.  Basically, resources that come
out of the System file are loaded in the System Heap, rather than the
Application Heap.

The System Heap under Multifinder is expandable, because application are
loaded towards the other end of memory as much as possible.  So if you start
opening DAs, the System Heap will start growing; as you close them, it will
shrink again.  (The about box in the Finder shows the current memory usage;
as you open and close DAs you can see the size of the System memory grow and
shrink.) 

The point I made before about the number of DAs, is that the System resource
map has to be loaded in the System Heap as well, so every DA and font
requires additional map space.  For example, the names of resources are in
the resource map.
