No, I meant the earlier patch which you rejected with the flag in MyProc. I
realize there were other issues but the initial concern was that it wouldn't
respond promptly because it would wait for CHECK_FOR_INTERRUPTS. But if
sigterm was never handled except at a CHECK_FOR_INTERRUPTS then that was never
a factor.
