    For iterators that can be run at major compaction, how can we exercise delete keys?

> Users often write iterators without fully understanding its limits and lifetime. Accumulo
should have an iterator fuzz-tester which will take user data and run the iterator under extreme
conditions.  For example, it should re-create and re-seek the iterator with every key returned.
 It could automatically compare results of such a run with the naive run, which seeks to the
beginning and scans all the data.
