Old space is still collected by one thread. Automatic memory management, also known as automatic garbage collection, is the practice of allowing the language implementation to keep track of used and unused memory, freeing the programmer from this burden. When zombies are enabled, a deallocated object's class is dynamically changed to be _NSZombie, and by default, the memory region is never marked as free, although this can be controlled separately. The Garbage Collection Handbook The Art of Automatic Memory Management - Garbage Collection: Algorithms for Automatic Dynamic Memory Management (운영체제와 컴파일러에 정통하� 분은 금방 보는 참고서일뿐 ㅡ. In languages without automatic memory management, the In contrast, C++ programmers manually specify where an object with dynamic extent is to be reclaimed by coding a delete statement. Java classes can have a finalize function. Java (and dominating majority of other modern languages) features automatic memory management aka garbage collection. CLR provides features such as automatic memory management (GC), exception handing, security, type safety, JIT (Just in time compiler for converting msil to native code) and more. Once instance of object becomes Parallel scavenge GC mode is using parallel implementation of young collection algorithm. Unlike JAVA garbage collection mechanism where the memory for allocated object is automatically reclaimed by system when it goes out of scope, in iPhone framework developer need to take care of releasing the memory for the object. This is a special mode of parallel scavenge collector in which it can dynamically adjust configuration of young space to adapt for an application.
