I think simple function used by all tests will be good.

Something like:

    def run_child(cpu_list=None):
        if cpu_list:
            taskset.set(os.getpid(), cpu_list)
        self.running.set()
        self.stop.wait()
Line 86:             # avoid race on startup: first do taskset, then notify
Line 87:             taskset.set(os.getpid(), cpu_list)
Line 88:             self.running.set()
Line 89:             while not self.stop.is_set():
