[cpp-threads] Fixing the thread type

[Alexander Terekhov]

IMO Boost.Thread is nothing but somewhat castrated pthreads in form
of a bit controversial thin object layer on top of pthreads legacy
stuff. Given that there seems to be some interest regarding
POSIX.C++,

We had a discussion about whether there should be a project
to develop a C++ binding to POSIX. We think that
we should investigate whether IEEE would be interested
in doing this.

I believe that the right thing to do is something along the lines
of C++ TR's <hardware> and <iohw.h>.

I mean

---
The implementation of the basic <iohw.h> hardware register access
interface on top of the <hardware> interface is mainly straightforward.
This section provides an example of how such an implementation
can be achieved.
---

in the sense of that the implementation of the basic/legacy
<pthread.h>/<cthread> interface on top of the <thread> interface
is also mainly straightforward...
