A big THANKS to all of you who responded so quickly to point out my 
absent-mindedness of not actually *declaring* my "capturing" ivar.  I 
can't tell you how many times I overlooked that simple fact when I was 
comparing my code to the sample code in the ObjC 2.0 docs.

Please consider me sufficiently flogged for being a bonehead.  (No 
actual noodles were harmed.)
