I am trying to make sure sched_setaffinity() works. That system call
allows you to restrict the execution of the calling thread on a (set
of) particular logical processor(s). So, after I call
sched_setaffinity(), I want to call smp_processor_id() to see if the
thread is indeed executing on a processor selected.
