[...] I'd also like to postulate that proposed solutions can rely on a new Python C API supplying a portable spelling of thread-local storage. We can implement that easily on pthreads and Windows boxes, it seems to me to cut to the heart of several problems, and I'm willing to say that Python threading doesn't work anymore on other boxes until platform wizards volunteer code to implement this API there too. FWIW, I am pretty confident that this can be done (read: copied) as Douglas Schmidt has implemented it (on more platforms than python supports ) in the Adapative Communication Framework (ACE): http://doc.ece.uci.edu/Doxygen/Beta/html/ace/classACE_TSS.html

We also have a TSS implementation in the Boost.Threads library. I haven't looked at the ACE code myself, but I've heard that every component depends on many others, so it might be easier to extract useful information from the Boost implementation.
