Hi Jonathon,
So, thanks for the quick response there.
The object in question is instantiated in my NIB and, though is not
visible, it has outlets to other objects (specifically an array
controller and a spinning circle thing). I figured that would be
strong enough to prevent collection.
That is not enough. The object needs pointers pointing *to* it in
order to be kept around.
Also, the self is obviously stored in SyncServices as it knows that
it's a callback-able class for when of tries to
client:mightWantToSyncEntityNames:.
If the syncservices docs claim to retain the object, then I'd file a
bug. Otherwise, you cannot assume that it will keep your object around.
I implemented the finalize method just now and, sure enough, the
object is getting collected.
I'll try making the object pop itself into a global to see if it
helps.

For example, in a classes init method, I get it to NSLog the self
pointer. Then, after some time, I see errors relating to the class.
Are you storing a reference to that instance in a "strong"
location, such as a global variable? Otherwise the garbage
collector has no idea that it might be used later on.
