Please explain... Would the pid be set erroneously as well ? Ignoring
the kernel-user space pointer issue, we're going to have a tight
pid + request_id relationship being maintained across multiple messages.
We'll also be depending on the pid events for clean up if an app dies.
So I hope pid is consistent.
