If you want to rely on consecutive system calls never seeing the same
timestamp, let alone PID reuse in the same timestamp -- for some generic

I can drop the timestamp and go back to the original "cookie"
generation that guaranteed unique ids for something like 2^48 system
calls per task.

I thought the timestamps just made it easier. But having to audit every
arch, may make that not the case.
