Just to be clear, suppose I have a large tape library with functioning
barcode reader and associated changer database.  Maybe 150 slots with
80 slots devoted to an amanda config, The 80 slots are filled with
reusable tapes but I've set my tapecycle to less than 80 for protection
against damaged or removed tapes.

I may at some point access the library, perhaps for non-amanda slots or
to do some recovery.  There is no attempt to follow the order from the
tapelist and change directly to the next ordered tape.  It is the
responsibility of the administrator to ensure that the changer gets
back to a correct slot position before amanda runs.  Because otherwise
it will use whichever of the 21 eligible tapes it hits first.  Bleech!
