The easiest way would be to replace NSObject's -init and -dealloc methods. The 
replacement of -init would then create a counter object (if it doesn't exist 
yet) when ever it is called, and increment it by one, then return the original 
-init. The new -dealloc would just decrement the object counter by one, then 
call the original -dealloc. To check, you would have to first swizzle the 
original -init and -dealloc with the new ones, run your test, dump the counter 
when its finished, then switch both methods back to the original.

Yes, it's a hackish way, but it works.
