Well, IMO, you need to free what you allocated in your own program. Think of a factory function that allocates new instances of objects. If you call that factory a lot of times, perhaps in event driven loop, without trying to clean up after yourself wrt freeing memory that has gone out of reference. Well, your memory usage will blow up, and allocating another object will fail... So, it does not matter if the OS frees memory that you use, but were to careless to clean up, during long runs. Try allocating objects in a loop without freeing anything... You will crash! ;^o
