    Description

      We added warnings to 1.2 (CASSANDRA-6042); for 2.0 we should go farther and drop requests (with an error logged) that exceed the threshold. Users who want to tread dangerously are free to crank the threshold up, but "I queried a lot of tombstones and Cassandra fell over" is possibly the number one way of killing Cassandra nodes right now.
