Milestone:  To Be Determined                 |   Component:  thread

 Keywords:  c++11 compliance thread dtor V2  |  
---------------------------------------------+------------------------------
 In order to be standard compliant the thread destructor should call
 terminate if joinable instead of detaching the thread.

 "30.3.1.3       thread destructor       [thread.thread.destr]

 ~thread();

 If joinable() then terminate(), otherwise no effects.
 [Note: Either implicitly detaching or joining a joinable() thread in its
 destructor could result in difficult to debug correctness (for detach) or
 performance (for join) bugs encountered only when an exception is raised.
 Thus the programmer must ensure that the destructor is never executed
 while the thread is still joinable. — end note ]"

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