-------------------------------------------------------------------
The test was checking if total off-heap memory usage since node start was below
the large column size (66060288 bytes), and it was passing on cassandra 2.2.
However, on 3.0 it was not passing (probably due to increase in off-heap memory
footprint), so I modified the test to check the memory usage delta instead
(before and after stress), which should be sufficient to identify if heap usage
grows proportional to column size.

> This test on large columns is failing:
> http://cassci.datastax.com/job/cassandra-3.0_dtest/lastCompletedBuild/testReport/largecolumn_test/TestLargeColumn/cleanup_test/
> and it's been failing for a while:
> http://cassci.datastax.com/job/cassandra-3.0_dtest/lastCompletedBuild/testReport/junit/largecolumn_test/TestLargeColumn/cleanup_test/history/
> I've reproduced the failure on OpenStack, so it's not just a CassCI problem.
