Yes, it will be in 1.35.0

The sourceforge CVS repository is no longer used. Boost development is
now done under subversion: go to http://svn.boost.org for details.

In the 1.35.0 code there is a function called native_handle() on the
thread object.

I'll be checking this stuff into the subversion trunk. I'll post here
when I do.
