    kernel - Refactor exis_terminate()
    
    * Change exis_terminate() to set the EXIS lock into a CACHED(0) state
      unconditionally, meaning that in one pseudo tick it will wind up
      in NOTCACHED and in two pseudo_ticks it will wind up in the
      TERMINATE (freeable) state.
    
      This is less confusing, and allows EXIS locks in their simplest form.
      We can add other inlines to perform more nuanced operations.
