Subject: [PATCH 09/11] parentpipe: make the ->close call more obvious
Date: Sat, 29 Jun 2019 19:59:49 +0000
Message-ID: <20190629195951.32160-10-e@80x24.org> (raw)
In-Reply-To: <20190629195951.32160-1-e@80x24.org>

We can close directly in event_step without bad side effects,
and then we also don't need to take a reason arg from worker_quit,
since we weren't logging it anywhere.
