commit 9ce673b69e82578044958f66d93dcaddb23f6e95

Author: Florian Weimer <fweimer@redhat.com>

    Do not scale NPTL tests with available number of CPUs

    On very large multi-processor systems, creating hundreds of threads

    runs into a test time out.  The tests do not seem to benefit from

    massive over-scheduling.
