Is there any reason for avoiding this treatment to %gs, apart that TLS code usually does not need it, even if the API allows for it to exist? I _do_ believe this patch fixes bug which can be tested (not verified everything), even if I wonder why you didn't look at the patch I sent to you time ago (I hadn't finished it, in truth, but there was most stuff - it had problems I couldn't debug at that time). -- Inform me of my mistakes, so I can add them to my list!
