Controls CPU affinity for the local process. If not set (0), affinity is not set. On multiprocessor machines, the recommended
setting is 1 (default), which will restrict the application to run on a single CPU. This is required to prevent inconsistent clock readings.
Allowing QSM to run on multiple CPUs, suhc as by leaving this option unset, is only safe if all the CPUs provide consistent
values of the RDTSC counter.
