I don't understand your point here...

Currently, given the performance requirements of OpenGL, our drivers
are one of the first users of the new ELF TLS implementation on Linux,
outside of libc itself.  Given the fact that this is a general solution
to a common problem, I strongly urge you to take it into consideration
when working on your threading libraries.  There are only going to be
more users of __thread variables as time goes on -- you can imagine
that many multithreaded user-space server applications will start using
this soon, instead of the clunky pthread TLS interface.
