_Yup, in fact, if I hadn't come up with the read[gf]sword() trick, my only other option would have been TLS (or the GetCurrentThreadId /pthreadself() approach in the presentation). TLS is fantastic, and it's definitely an intrinsic part of the solution (the "Y" part of "if we're a parallel thread, do Y"), but it definitely more costly than a simple FS/GS register read.

I think you should be able to just take the address of a static __thread variable to achieve the same thing in a more portable way.
