You have probably simply not understood when / how autoreleased objects
are deallocated. I suggest that you find the documentation and refresh
your understanding of Cocoa memory management.
The reason that the memory management is not working as automatically
as you might be used to in a simple Cocoa application is that you're
running in a tight loop, not allowing the regular run loop to run to
completion. It is only at the end of the current run loop that the
"default" autorelease pool, the one you "get for free" from the kit, is
released, and the objects referenced by it in turn released. If you
never allow for this to happen you'll simply collect autoreleased
objects until you run out of memory.
Search on Google for "autorelease loop" for tips and tricks on how to
deal with this.
