You covered it in memory management, but restatement might clarify.
These instances are used to make objects such as dialog boxes or quicktime windows on the screen, say attached to instantiations of IB, but when no longer needed to build into stuff in the nib file can go away but the nib associations hang around until the program quits.
I don't like the way I worded the above and think that maybe someone could make a better brief.
