  SVN rev 212115 on 2010-09-01 20:32:47Z by mdf
  
  Fix a bug with sched_affinity() where it checks td_pinned of another
  thread in a racy manner, which can lead to attempting to migrate a
  thread that is pinned to a CPU.  Instead, have sched_switch() determine
  which CPU a thread should run on if the current one is not allowed.
  
  KASSERT in sched_bind() that the thread is not yet pinned to a CPU.
  
  KASSERT in sched_switch() that only migratable threads or those moving
  due to a sched_bind() are changing CPUs.
  
  sched_affinity code came from jhb@.
