Subject: [PATCH 1/2] tests: replace select/usleep calls with tick()
Date: Mon, 12 Dec 2022 04:22:00 +0000 [thread overview]
Message-ID: <20221212042201.510414-2-e@80x24.org> (raw)
In-Reply-To: <20221212042201.510414-1-e@80x24.org>
This makes it easier to identify places in tests which cause
unnecessary slowdowns doing busy waits.
