sched_pin is different than sched_bind, sched_pin only pins current thread on
current cpu, but sched_bind allows a thread to migrate to another CPU, after
the sched_bind returns, the thread should already be running on the specified
CPU, it makes it possible that a thread can iterate through all available
CPUs.
