    sys/bus/cam          cam_sim.c cam_sim.h 
  Log:
  Do not destroy the device queue, it is needed by the peripheral code
  (e.g. scsi/scsi_da.c, etc) even if the backend hardware has disappeared.
  When cam_sim_free() is called, set up a dummy poll and action callback
  and make the action callback generate an I/O error.
  
  This allows things like filesystem mounts of USB memory sticks to start
  returning I/O errors instead of blocking forever if the stick is pulled.
