When a QScriptValue is initially not bound, its private will be allocated from the normal heap (and not from the engine's pool of privates, because there is no engine at this point). But when a value is later bound (e.g. by setting it as a property of an object, or by passing it as argument to QScriptValue::call()) and is subsequently destroyed, its private will be handed to the engine, which will add it to its free-list (hence the memory is not freed). This allocation/deallocation asymmetry causes this list go keep growing. The solution is to limit the size of the free-list, and free the memory of the private immediately when the list has reached a certain size.
