From c310ade9f8d389bcd82ae2159340170ade79ad77 Mon Sep 17 00:00:00 2001 From: Antonio Cunei Date: Tue, 30 Jan 2018 23:59:37 +0100 Subject: [PATCH] Allow the full tests/fork-parallel to pass on less than four cores The test will be meaningless on less than four cores, but the scripted test will pass. On four or more cores, the test wil test testForkedParallel as expected.
