I was assuming rb_erase() was setting things up like list_del_init, but the fact that thread__delete() was being sucessfull is because the last thing before deleting is to remove the thread from the machine->dead_threads list, using list_del_init(), that has the same effect as using rb_erase_init()... Introduce this function so that we can use it when removing objects from rb_trees. Then we will be able to BUG_ON(still on a list) in destructors.
