SCSI reconnect
     
         The ability of a {SCSI initiator} to initiate new
        transactions before earlier ones have completed.  A target or
        initiator can disconnect from the bus when it experiences a
        delay in completing a task so that another device can use the
        bus.  It can reconnect later and complete the task.
