Description

A number of the upgrade_tests in dtest are flapping with data integrity bugs. For instance:

http://cassci.datastax.com/view/cassandra-3.0/job/cassandra-3.0_dtest/422/testReport/upgrade_tests.cql_tests/TestCQLNodes3RF3/conditional_delete_test/history/

http://cassci.datastax.com/view/cassandra-3.0/job/cassandra-3.0_dtest/421/testReport/upgrade_tests.cql_tests/TestCQLNodes3RF3/cas_and_list_index_test/history/

This needs further digging to get good debug information; it could well be, e.g., a race condition in the test. I have not reproduced locally.
