Re: [RFC][v8][PATCH 0/10] Implement clone3() system call

I stand corrected by Suka: a pid-specific clone does not change
last_pid. Therefore, given that 'restart' only creates tasks with
pid-specific clone, this should be safe for c/r.

Exactly.  We can preserve the existing guarantees and keep the ability
to restore any pid (at least in a fresh pid namespace).
