This, and the other stuff you wrote, are very good points.

Without checking the VM sources, my guess is that _AddSlots: scans 
through the whole memory updating all pointers to the changed object. 
This was a key decision in the object memory design - that the heap(s) 
should be scanned word by word instead of object by object and field by 
field within the object.

This works very well with everything in RAM, but like #allInstances and 
friends from Smalltalk it doesn't like virtual memory.
