That is one possible design, but it's not the only one.  Another design is
to make the thread object reference counted, and let the thread itself own
one reference.

If that is true, it makes sense to call it "boost::thread::ref" and make it
copyable.  This does not exclude the possibility of a reference counted
thread object as described above, either as part of the interface or as an
implementation detail.
