Read the Cocoa Fundamentals Guide: http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/CocoaFundamentals/CocoaObjects/CocoaObjects.html#//apple_ref/doc/uid/TP40002974-CH4-SW39 From the section "How Memory Management Works": "If you are developing an application you may not need to set up an autorelease pool; the Application Kit automatically sets up an autorelease pool scoped to the application’s event cycle." This explains the behavior you're seeing: every time your application goes through its event cycle, the main autorelease pool is drained.
