You have discovered the interface between the VM and the Image. Some  
objects must be known to the VM, and the specialObjects array holds  
them:

Smalltalk specialObjectsArray

For example, the first three entries are nil, true, and false - the VM  
needs nil to initialize instance variables of new objects, and the  
booleans for conditional jumps.

Also see #recreateSpecialObjectsArray
