While we're on the subject, another trick I often use is a "sacrificial object". I'll create a subclass of NSObject that overrides retain, autorelease, and release. (Or, I'll override these in an existing class I'm having problems with.) Something like this:
- (id)retain
{
return ([super retain]);
}
- (void)release
{
[super release];
}
...
I then throw an autoreleased instance of this object into a collection.
The only purpose here is that I can now set a breakpoint at release and use the debugger to see when and where the object is getting released. This is sometimes faster than trying to plow through an ObjectAlloc graph.

Your gut is correct. Unless you later release or autorelease an object created with alloc+init, it will be overretained.

Good luck,
