Subject: [PATCH 01/10] lei q: delay worker spawn
Date: Thu,  4 Feb 2021 00:59:21 -0900	[thread overview]
Message-ID: <20210204095930.20278-2-e@80x24.org> (raw)
In-Reply-To: <20210204095930.20278-1-e@80x24.org>

Now that --stdin support is sorted, we can delay spawning
workers until we know the query is ready-to-run.
