when you mean that does it mean simply replacing?

we should pay attention to SystemTracer when we do that

The behaviour of both methods is different. findElementOrNil: raises an  
error when a free slot is not found, while scanFor: returns 0.

I understand that this should never happen, but still I think it would be  
better to raise an error than returning 0.

Looking at the senders, no one seems to check the returned value, assuming  
that it will be different from 0.

There is no should, it will never fail to find a free slot.
