| Yes, this is problem... I doubt we can rely on !si_pid here.

BTW, rather than clearing SIG_FROM_USER in send_signal(), can we
keep it till we dequeue the signal ? Yes, collect_signal() would
need to consider this flag. But when we dequeue, we can note that
it was from user and use that in the siginfo_from_ancestor() ?
