Subject: [PATCH 05/19] ipc: do not die inside wq_worker child process
Date: Sun,  7 Feb 2021 08:51:47 +0000	[thread overview]
Message-ID: <20210207085201.13871-6-e@80x24.org> (raw)
In-Reply-To: <20210207085201.13871-1-e@80x24.org>

die() in a child zips up the stack into the parent, which is
undesirable behavior.  We're going to exit anyways, just warn
and let exit(1) happen due to $@ being set.
