Thread has just become a zombie or is about to self-reap. If positive,
<em class="parameter"><code>signal</code></em> is the signal number just sent to the parent (usually <code class="constant">SIGCHLD</code>).
If <em class="parameter"><code>signal</code></em> is <code class="constant">DEATH_REAP</code>, this thread will self-reap. If <em class="parameter"><code>signal</code></em> is
<code class="constant">DEATH_DELAYED_GROUP_LEADER</code>, this is a <code class="function">delayed_group_leader</code> zombie.
The <em class="parameter"><code>death_cookie</code></em> was passed back by <code class="function">tracehook_notify_death</code>.
</p><p>
If normal reaping is not inhibited, <em class="parameter"><code>task</code></em>->exit_state might be changing
in parallel.

Called without locks.
