(*) the loader needs to set some values into symbols and the thread scheduler needs code to allocate a segment of 'M' bytes every time it rceates a new thread and set a pointer to it.. (it already allocates some info but it needs to allocate 'M' bytes more) where 'M' is the statically detirmined TLS size. The next step would be to add code to the dynamic linker to be able to allocate TLS segments to modules as it loads them. The TLS spec pretty much outlines what needs to be done.. We NEED to do this.. it is not a "may be nice" item. TLS is becoming standard on many platforms and more and more software is ASSUMING it is present.
