From 9d273344238330d634acb4a7d427a8fb732ae62e Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Wed, 30 May 2018 20:28:04 -0700 Subject: [PATCH] bpo-33532: Fix multiprocessing test_ignore() (GH-7262) Fix test_ignore() of multiprocessing tests like test_multiprocessing_forkserver: use support.PIPE_MAX_SIZE to make sure that send_bytes() blocks.
