+Item 41: Least recently used device selection for tape drives in autochanger.
+Date:    12 October 2009
+Origin:  Thomas Carter <tcarter@memc.com>
+Status:  Proposal
+
+What: A better tape drive selection algorithm for multi-drive 
+      autochangers. The AUTOCHANGER class contains an array list of tape 
+      devices. When a tape drive is needed, this list is always searched in 
+      order. This causes lower number drives (specifically drive 0) to do a 
+      majority of the work with higher numbered drives possibly never being 
+      used. When a drive in an autochanger is reserved for use, its entry should 
+      be moved to the end of the list; this would give a rough LRU drive 
+      selection.
+
+Why:  The current implementation places a majority of use and wear on drive 
+      0 of a multi-drive autochanger.
