Of course the kernel has no way of knowing that the bad news has not already
happened and that continued waiting is not just making things worse.

It would seem sensible to be able to kill
any process that is not reset immune.
For that matter, it would seem sensible to be able to
kill any process that is not power button immune.
Perhaps kill --with-extreme-prejudice and kill --with-all-prejudice  .

Under what circumstance would killing a waiting process
be worse than a process that should have waited,
but terminated instead?
