A return value >= 0 means call <code class="function">do_notify_parent</code> with that signal
number. Negative return value can be <code class="constant">DEATH_REAP</code> to self-reap right
now, or <code class="constant">DEATH_DELAYED_GROUP_LEADER</code> to a zombie without notifying our
parent. Note that a return value of 0 means a <code class="function">do_notify_parent</code> call
that sends no signal, but still wakes up a parent blocked in wait*().
