Comment 4 for bug 1379072

The callback has the wrong signature: http://eventlet.net/doc/modules/greenthread.html

 link(func, *curried_args, **curried_kwargs)

    Set up a function to be called with the results of the GreenThread.

    The function must have the following signature:

    def func(gt, [curried args/kwargs]):

since the patch that introduced this is lined up for stable, I do the same for this.
