I agree, and it should be able to clean up non-boost threads as well -
consider what happens if you're writing a library, and not a program - you
then have no control over who creates threads or how they do so.  I believe
it would be unacceptable to say "you can only use this library if you also
use Boost.Threads"; in such cases thread_specific_ptr is exceptionally
useful IMO.
