Norbert, you are confusing threads with fibers. OS Threads have never been, nor will ever be, "light-weight" in any sense of the word.
What I had in mind were discussions about OSes that make thread creation extremely cheap, but indeed: OS threads will probably always carry sufficient overhead to leave plenty of room for application-level mechanism...
Does anyone know how expensive thread creation is for typical and for experimental OSes? How does this compare to the overhead of initializing thread-local data? I.e.: How much should one actually worry about TLS?
