  25  *      History:
  26  *
  27  *      Fixed sleep integration problem. sleep was not properly
  28  *      handling thread states of THREAD_INTERRUPTED and
  29  *      THREAD_MUST_TERMINATE, so callers of sleep were getting
  30  *      confused and many times looping.  This fixes the (in)famous
  31  *      unkillable gdb problem, the PB (and other processes) don't
  32  *      terminate, and more. Removed debugging kprintf left in
  33  *      bcopy code
