No, it's not finished yet. Detlef posted a draft on the WG21 wiki, but  
it's password protected. The paper is strongly based on N2276  
(http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2276.html),  
but has promise and packaged_task return a unique_future (like  
unique_ptr), which can be moved into a shared_future if required.  
unique_future allows the result to be moved out (rather than copied),  
but shared_future doesn't. Also, all the thread pool and thread  
launching stuff has been stripped, as that's destined for TR2, whereas  
promise/unique_future/shared_future/packaged_task might make it into  
C++0x.
