Subject: [PATCH 2/5] deflater: avoid wasting an ivar slot on @closed
Date: Thu, 29 Jun 2017 02:19:12 +0000	[thread overview]
Message-ID: <20170629021915.22517-3-e@80x24.org> (raw)
In-Reply-To: <20170629021915.22517-1-e@80x24.org>

We can merely set the @body to nil ensure we do not call close
on the @body, twice.  Saving an ivar slot can save 8 bytes
per object at minimum, and this makes me feel more comfortable
about using another ivar for the next commit.
