According to Stevens Post using the "Thread Information block" which is 
addressed by FS is documented and thus needs to be working for 256 
TLS-Slots (whatever that means) in NT (and supposedly higher). Who cares 
about Win9x :) .

No idea about Win64.

BTW what about GS ? If same is just restored after preemption, this 
could be used by the compiler to point to the Threadvar area.
