Comment(by cyberfox@…):

 Greetings,

 Ah; thank you!  That's what I needed to know.

 I figured there was something deeper that I was missing, but being new to
 Cocoa, I didn't even know what to look for.

 The key line appears to be

 ''The data source is in turn responsible for retaining all of the objects
 it provides to an outline view, and updating the outline view when there’s
 a change to the model. It is therefore not safe to release the root
 item—or any children—until you’re no longer displaying it in the outline
 view.''

 Presumably they're being released by the GC in between accesses.  Thanks
 very much for the pointer!
