    rseq/selftests: Adapt number of threads to the number of detected cpus · 0a7dc82e
    Mathieu Desnoyers authored
    On smaller systems, running a test with 200 threads can take a long
    time on machines with smaller number of CPUs.
    
    Detect the number of online cpus at test runtime, and multiply that
    by 6 to have 6 rseq threads per cpu preempting each other.
