I need to go over this in some detail and figure out the remaining race, and worse yet how to fix it without the mess of existing locks turning it into something nasty. I think I understand what is needed but I don't want to be doing it as a mad panic for 3.6. On the bright side I think it explains the other tty lock splitting mysteries. Alan
