GTMOAuth2WindowController in a modal session

[GoogleCodeExporter]

What steps will reproduce the problem?

I usually start a login sheet from a modal dialog and with the current 
implementation this causes problem during the step of receiving tokens.

To solve I need this:

    fetcher = [GTMHTTPFetcher fetcherWithRequest:request];
+     [fetcher setRunLoopModes: [NSArray arrayWithObjects:NSDefaultRunLoopMode, 
NSModalPanelRunLoopMode, nil]];

in +[GTMOAuth2SignIn userInfoFetcherWithAuth:] and -[GTMOAuth2Authentication 
beginTokenFetchWithDelegate:didFinishSelector:]

or at least provide a method to set the desired runLoopModes, as in 
GTMHTTPFetcherService

Thanks.

You can set the auth object's fetcherService property and assign run loop modes 
to the fetcher service, and the gtm-oauth2 methods will get the fetcher from 
that fetcher service.
