-------------------------------------------------------------------

I've tried to track the problem down, although it's flaking quite infrequently. So far I have
several "working hypotheses", one of them is that that we have name clashes. There's some
evidence to name clashes [here|http://cassci.datastax.com/view/Dev/view/carlyeks/job/carlyeks-ticket-11803-3.X-testall/lastCompletedBuild/testReport/org.apache.cassandra.index.internal/CassandraIndexTest/indexOnFirstClusteringColumn_compression/]
and [here|http://cassci.datastax.com/job/ifesdjeen-11803-test-fix-trunk-testall/1/testReport/junit/org.apache.cassandra.index.internal/CassandraIndexTest/indexOnFirstClusteringColumn_compression/].

(dtest is not applicable since only test code was changed)

Since the test fails quite infrequently, I just keep re-running with some code wrapped around
the mentioned failure to re-try multiple times to gather more data. However, with this patch
I could not reproduce after 30 test runs. I'll keep trying though.
