I don't think the amount of memory listed under "System" indicates the 
size of the System Heap.  I think that number in the total of the memory 
that isn't otherwise accounted for.  (For example, any INIT that uses 
memory above BufPtr will contribute to the System total.)

The RAM cache is proably the #1 cause of unexpected memory usage.  One 
should also check to see if a debugger is installed.  Macsbug, for 
example, takes a fari amount of memory (50-60K I think), which can make 
the difference in some cases.
