No time out on GoogleWebAuthorizationBroker.AuthorizeAsync?

What steps will reproduce the problem?
1.
 UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets { ClientId = clientId, ClientSecret = clientSecret }                                                                                            , scopes , "x", CancellationToken.None                                                      , new FileDataStore("Daimto.com.Auth.Store")).Result;
2. The Authentication window will open
3. Either close the browser or do nothing.   Just wait.  (Don't click accept or 
cancel)

What is the expected output? What do you see instead?

At some point I would expect the code to timeout and the application to either 
throw an exception or at the very least return to the application.   I have 
left the application running for 10+ minutes.  It never returns it just sits 
there waiting for a response.

What version of the product are you using?
What is your operating system?  windows 7 
What is your IDE?  Visual studio 10
What is the .NET framework version?  4.0

Please provide any additional information below.
