I guess it depends on what "detach" means.  I don't know pthreads, but
on Windows issue then is just , I think, whether to just close handle
in the destructor or wait for the thread to complete.

I think for the thread::ref doing a join() in the destructor would be
silly, what with many copies of the ref possibly spread all over the
program, but it might make sense for the thread destructor, assuming
there is even a thread class to have a destructor.
