From a9b51b8d9f7a0fa398d979aa5df5438770a38448 Mon Sep 17 00:00:00 2001 From: Diego Russo Date: Fri, 7 Mar 2025 21:10:02 +0000 Subject: [PATCH] gh-130917: update timer and workload in test_signal (GH-130918) The workload to advance the virtual timeout is too lightweight for some platforms. As result the test goes in timeout as it never reaches the end of the timer. By having a heavier workload, the virtual timer advances rapidly and the SIGVTALRM is sent before the timeout.
