Ok.  I think this has exactly the same effect as my patches get by
introducing checks and invariants relating to last_siginfo.  To me that was
less ambitious than introducing a new value for the state field, because I
am not entirely sure I grok how that is used everywhere.  If you think that
adding a new TASK_TRACED state will not have lots of gotchas, I am happy to
take a crack at it.


Thanks,
Roland
