All this leads me to the paragraph about top-level objects under
garbage collection:
===
Mac OS X - garbage collected memory model
Most objects in the graph are kept in memory through strong references
between the objects. Only the top-level objects in the nib file do not
have strong references initially. Thus, your code must create strong
references to these objects to prevent the object graph from being
released.
===
Does this mean that there's a race between the NIB loader's need to
create a strong reference and the GC thread's imperative to collect
the object before it is referenced?
