  Log:
  Under certain circumstances, we were calling kmem_free() from
  i386 cpu_thread_exit().  This resulted in a panic with WITNESS
  since we need to hold Giant to call kmem_free(), and we weren't
  helding it anymore in cpu_thread_exit().  We now do this from a
  new MD function, cpu_thread_dtor(), called by thread_dtor().
