Delegate array should not retain delegates

[jasperblues]

You can make a weak reference array as follows:

@implementation NSMutableArray (EngineEventSubscriber)

• (id)mutableArrayUsingWeakReferences
  {
  return [self mutableArrayUsingWeakReferencesWithCapacity:0];
  }
• (id)mutableArrayUsingWeakReferencesWithCapacity:(NSUInteger)capacity
  {
  CFArrayCallBacks callbacks = {0, NULL, NULL, CFCopyDescription, CFEqual};
  // We create a weak reference array
  return (__bridge id) (CFArrayCreateMutable(0, capacity, &callbacks));
  }
