I'm not aware of such a document. I have proposed to Anthony and Ion a plan to make Boost.Thread and Boost.Interprocess(sync part) more uniform and closer to the proposed C++0x. I gues we will get it once Boost.Chrono and Boost.Move are included into Boost.

The following doesn't pretend to be exhaustive, but expect would give you a good idea.

Additions of Boost.Thread
* thread interruption
* Shared mutexes and locks
* Thread groups
* lock and try_lock applied to range of Mutexes
* thread_specific_ptr
* future callbacks

Missing or different in Boost.Thread:
* system_error exceptions versus specific Boost::Thread exception 
* even if Boost Thread provides move semantics, it should be great to use Boost.Move in a uniform way.
* use of chrono interface versus ptime
* cv_status
* std::atomic_future/std::shared_future versus boost:future
* thread_local

Stefan Strasser proposed a static_thread_specific_ptr class that should be a closer emmulation of thread local storage than boost::thread_specific_ptr.

Best,
Vicente
