I noticed this thread before sending my patch. I don't think
we are trying to solve the same problem:

a) I only care OOM kill, not other SIGKILL cases
b) I don't set the frozen process state to TASK_KILLABLE
   at all

I think Bartlomiej was trying to make frozen processes
killable by user-space SIGKILL, which is beyond my interest.

Thanks.
