Milestone:  To Be Determined  |   Component:  thread  
  Version:  Boost 1.48.0      |    Severity:  Problem 
 Keywords:                    |  
------------------------------+---------------------------------------------
 In order to be standard compliant the thread move assignment should call
 terminate if joinable instead of detaching the thread.

 "30.3.1.4       thread assignment       [thread.thread.assign]

 thread& operator=(thread&& x) noexcept;

 Effects: If joinable(), calls terminate(). Otherwise, assigns the state of
 x to *this and sets x to a default constructed state."

 This behavior is incompatible with the current version, so it shall be
 activated by a specific define, i.e., BOOST_THREAD_VERSION=2.
