  Log:
  Sometimes the vty switching has to be delayed; the vty
  to be switched to is saved in sc->delayed_next_scr and
  the actual switch is performed later.  It was possible
  to get into the endless loop when attempting to switch
  to a closed vty (which is not allowed and beep-alerted
  when attempted) and when the visual beep was in effect.
  This caused sc->delayed_next_scr to never be reset and
  endless attempts to switch to a closed vty and endless
  visual beeping.  How to repeat:
  
  - boot into single-user
  - run "kbdcontrol -b visual"
  - quickly press Alt+F2 two times
