I don't have a resolution to this puzzle, but I think we should probably try to avoid generating test failures on single-core machines (where, I assume, there is limited benefit from increasing the number of threads). While modern CPUs are generally multi-core, there is nothing to stop processes being bound to a subset of cores (or indeed, coreutils being built in a VM which is only allowed to use one core).
