I cannot speak for him, but sometimes it is easier to just let the OS do stuff for you. That being said, if that is what he wants, it would be trivial to do using thread specific data:

The GNU extension is just a special case of TSD that was implemented to aid debugging as far as I can tell. It is separate from the pthreads functionality for implementing this though.
