 \subsection{Tape drive pre-emption}
 A background task that repacks or verifies a whole tape can take several hours.
 Such long duration background tasks must be pre-empted when higher priority user
-tasks arrive in order to meet the latency requirements of users.  The tape
-daemon will keep polling the scheduling information at a low rate and interrupt
-a low priority background task if a higher priority one is available to replace

 This mixing of high and low priority tasks previously had to be handled by hand or \textit{ad hoc}
 scripts in CASTOR.
