i think you all are missing the point, i want to monitor the retain

you're suggesting are debugging aids, i want to be notified atleast
every time retainCount changes, preferably only when it reaches 0, and
it should work while deployed on "vanilla" installs of os x..
is there any way to monitor retainCount for an object?
i'm writing a file based NSMutableArray subclass, and i would like
it
if objectAtIndex: could return the same object throughout the
object's
lifetime, to preserve memory etc..
Ok didn't review your original post...
I suggest setting up a object cache that use weak references to the
cached object and how those objects send out a notification when they
get deallocated or something along those lines. It is not clear what
objects you are trying to deal with (your own or not), etc. Anyway
consider the following...
