Extract from Boost.Thread documentation at
http://www.boost.org/doc/libs/1_42_0/doc/html/thread/thread_management.html#thread.thread_management.thread.multiple_argument_constructor

"Thread Constructor with arguments

template <class F,class A1,class A2,...>
thread(F f,A1 a1,A2 a2,...);

Effects:

    As if thread(boost::bind(f,a1,a2,...)). Consequently, f and each an
are copied into internal storage for access by the new thread."

So whether the string temporaries are destroyed is irrelevant; my_thread
function will be called with *copies* of those temporaries.
