  31  *      History:
  32  *
  33  *      Fixed sleep integration problem. sleep was not properly
  34  *      handling thread states of THREAD_INTERRUPTED and
  35  *      THREAD_MUST_TERMINATE, so callers of sleep were getting
  36  *      confused and many times looping.  This fixes the (in)famous
  37  *      unkillable gdb problem, the PB (and other processes) don't
  38  *      terminate, and more. Removed debugging kprintf left in
  39  *      bcopy code
