Comment (by viboes):

 The issue is more complex than it seems at a first glance. From the
 documentation it seems that the callback should be called each time a wait
 function is called.


 {{{
 "Effects: Store a copy of f with the asynchronous result associated with
 *this as a wait callback. This will replace any existing wait callback
 store alongside that result. If a thread subsequently calls one of the
 wait functions on a future or boost::shared_future associated with this
 result, and the result is not ready, f(*this) shall be invoked."
 }}}
