Newbie missed the last line of thread::join()

I'm afraid this thread was started by one of my "senior moments".  When
reading ~thread() and join(), I flipped a bit and "saw" join() handled
m_joinable == true and ~thread() handled m_joinable == false.  THAT's why I
thought join() had to be called.  Your post caused me to go back and read it
again.  Now I'm *REALLY* embarrassed.

Thanks for getting me started down the right track.
