* TIB_INIT(tib, dtv)

* TIB_COPY(tib, oldtib)
* Copies oldtib to tib, (re)initializing the internal members

* TIB_TO_THREAD(tib)

*
* TIB_GET()
* Short-hand for TCB_TO_TIB(TCB_GET())
*
* TIB_THREAD()
* Returns a pointer to this thread's struct pthread
*
* TIB_EXTRA_ALIGN
* On TLS varaint 2 archs, what alignment is sufficient
* for the extra space that will be used for struct pthread?
*
* The following functions are provided by either ld.so (dynamic) or
* libc (static) for allocating and freeing a common memory block that
* will hold both the TIB and the pthread structure:
* _dl_allocate_tib(sizeof(struct pthread), flags)
* Allocates a combined TIB and pthread memory region.
* The first argument is the amount of space to reserve
* for the pthread structure; the second argument is
* either zero or DAT_UPDATE_CURRENT, the latter meaning
* this call is to update/replace the current thread's
* TIB. Returns a pointer to the TIB inside the
* allocated block.
*
* _dl_free_tib(tib, sizeof(struct pthread))
* Frees a TIB and pthread block previously allocated
* with _dl_allocate_tls(). Must be passed the return
* value of that previous call.
