Hrm, I think I'm confused.
The original Hurdish ancestor only has to remain alive for long enough
for proc to establish its record and copy the owner ID. If the kernel
actively notifies proc as soon as the process is created with this
information, we can be guaranteed it gets captured and recorded.
What does it matter what happens later?
