The thread_dev branch in CVS contains a number of changes to the
thread_specific_ptr / tss implementation that I would like to move to
the main branch. I plan to look at it more carefully before I do so,
but will anyone interested please take a look at the implementation on
the thread_dev branch to see if has any problems (or if there are
known problems that it doesn't fix)? It contains changes to fix a
number of issues with the current implementation, including, among
others:

1) thread_specific_ptr::reset() doesn't check error:
http://lists.boost.org/MailArchives/boost/msg55713.php.

2) Double deletes:
http://lists.boost.org/MailArchives/boost/msg50266.php,
http://lists.boost.org/MailArchives/boost/msg50543.php,
http://lists.boost.org/MailArchives/boost/msg30433.php,
http://lists.boost.org/MailArchives/boost-users/msg05531.php.

3) Not enough tss keys/slots:
http://lists.boost.org/MailArchives/boost/msg55376.php,
http://lists.boost.org/MailArchives/boost/msg55712.php.

4) Ability to register custom cleanup functions.
