Date: Thu, 19 May 2016 17:45:43 -0400 [thread overview]
Message-ID: <1463694357-6503-7-git-send-email-dturner@twopensource.com> (raw)
In-Reply-To: <1463694357-6503-1-git-send-email-dturner@twopensource.com>
From: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>
This allows signal handlers and atexit functions to realize this
situation and not clean up.
