From e6ce346d0791410a2e6ec9df1bc35e6acd4bca18 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Netto Date: Thu, 1 Jun 2023 12:59:19 -0300 Subject: [PATCH] stdlib: Tune down fork arc4random tests There is no fork detection on current arc4random implementation, so use lower subprocess on fork tests. The tests now run on 0.1s instead of 8s on a Ryzen9 5900X. Checked on x86_64-linux-gnu.
