From c8ff3ec3079eefa45a6ad726b4af083f354a000f Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Wed, 4 Jul 2018 11:49:41 +0200 Subject: [PATCH] bpo-34040, multiprocessing: Fix test_forkserver_sigkill() (GH-8081) Fix test_forkserver_sigkill() of test_multiprocessing_forkserver: give more time to the first child process to complete, double the sleep in the parent process. Reduce also the child process sleep from 1000 ms to 500 ms, to not change the total duration of the test.
