Good thinking, Frédéric!  Yes, I remember reading in a Mike Ash Friday Q&A that 
recent versions of OS X use tagged pointers for NSNumbers, and the strings 
which I tested are indeed constant strings.  What you say seems quite likely.

I still don’t understand how a managed object whose retain count is 14 could 
have deallocated attributes, though.  Need to read some more.
