Here are two options:
  1) Construct the asynchronous wrappers explicitly, as in:
       tp.add(make_asynchronous(boost::bind(f_, t1), the_thread_pool));

  2) Use another wrapper that is recognized by the asynchronous wrappers,
       tp.add(in_thread_pool(the_thread_pool, boost::bind(f_, t1)));

     in_thread_pool will return some simple wrapper around the thread pool and
the function object. Then the asyncronous wrapper can recognize this class
and extract the thread pool and function object directly.
