Hi,
I can see in the release notes that in Boost 1.52 boost::thread's
destructor calls terminate if joinable, in order to conform to C++11
specification. I am not sure if this is the best course of action.
My understanding -- form the C++ Committee papers and informal
presentations -- is that the reason for introducing a  'terminating
destructor' was the lack of thread cancellation/interruption functionality.
Thread interruption is supposed to be the preferred behavior for thread's
destructor. std::thread does not support interruption (for some reasons),
but boost::thread does (this is already a departure from C++11), so
shouldn't the latter prefer to interrupt a joinable thread in the
destructor?

Regards,
&rzej
