From 95e616aee099949a3707ec487dfc87b1eae65876 Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Mon, 25 Sep 2023 17:34:00 -0700 Subject: [PATCH] [3.11] gh-109401: Fix threading barrier test_default_timeout() (GH-109875) (#109877) gh-109401: Fix threading barrier test_default_timeout() (GH-109875) Increase timeouts. Barrier default timeout should be long enough to spawn 4 threads on a slow CI.
