Crash on reachability change

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Place an AdWhirlView on a UIView using addSubview
2. Remove the AdWhirlView when unloading the parent view
3. Change connectivity

What is the expected output? What do you see instead?
Expected = nothing.  Instead = crash as follows:

What version of the product are you using? On what operating system?
SDK 3.0.0

Please provide any additional information below.

Here's the line in the AWNetworkReachabilityWrapper where the error took place:

  // notify delegate that host just got reachable
  if (self.delegate != nil && [self.delegate respondsToSelector:
                                    @selector(reachabilityBecameReachable:)]) {
    [self.delegate reachabilityBecameReachable:self];
  }
}

respondsToSelector:]: message sent to deallocated instance 0xb1ca430

I'm guessing the notification request isn't being canceled when the view is 
unloaded.
