Subject: [PATCH 08/10] net_reader: mic_get: reuse connections if cache enabled
Date: Mon, 22 Feb 2021 08:22:57 -0300
Message-ID: <20210222112259.32402-8-e@80x24.org> (raw)
In-Reply-To: <20210222112259.32402-1-e@80x24.org>
We only enable {mic_cached} in WQ workers, and those
aren't expected to fork again going forward. So cache
here avoid a penalty for the non-augmenting (imap_delete_all)
call with "lei q"
