Thinking about this. As contingency planning if there is something in user space that actually somehow cares about pdeath_signal, from a threaded parent we can add a pdeath_signal list, to the task_struct and get rid of the rest of the complexity. I think I want to wait until someone screams first. This does very much mean that we can remove the complexity of a per thread ->children without fear, of having to revert everything.
