Change History
==============
+0.4.0 2009-09-08
+----------------
+
+- The previous version deleted too many objects at a time, which could
+ put too much load on a heavily loaded storage server.
+
+ - Add a sleep or allow the storage to rest after a set of deletions.
+ Sleep for twice the time taken to perform the deletions.
+
+ - Adjust the deletion batch size to take about .5 seconds per
+ batch of deletions, but do at least 10 at a time.

0.3.0 2009-09-03
