Does this code freeze your box as well:

#include <native/task.h>
#include <sys/mman.h>

main()
{
    RT_TASK task;

    mlockall(MCL_CURRENT|MCL_FUTURE);
    rt_task_shadow(&task, "crash", 1, 0);
    rt_task_sleep(1000000000ULL);
    system("ls -l");
    rt_task_sleep(1000000000ULL);
    printf("rt_task_sleep done...\n");
}

Or what is different with your test case? I got hold of P4 2.8 GHz
meanwhile, but the box still prefers to run the code without troubles.
