From 38399bd84f797be2752316821fae5412259460a3 Mon Sep 17 00:00:00 2001 From: Sam Gross Date: Tue, 12 Mar 2024 20:11:58 -0400 Subject: [PATCH] gh-116682: stdout may be empty in test_cancel_futures_wait_false (GH-116683) If the `shutdown()` call happens before the worker thread starts executing the task, then nothing will be printed to stdout.
