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

After reverting to batching by replica rather than just by partition key, see discussion on CASSANDRA-9303, the problem _almost_ disappears. 

I think there is some other issue, it happened twice all day long and I ran these bulk import tests pretty much all day fixing other issues for CASSANDRA-9303. In both cases the Cassandra processes lock the CPU, both times on 2.2 HEAD despite running several tests on TRUNK as well. 

I'm attaching some log files.

After reverting to batching by replica rather than just by partition key, see discussion on CASSANDRA-9303, the problem becomes very hard to reproduce, about twice out of approximately 50 times. Both failures were on 2.2 HEAD and never on TRUNK despite running about half of the tests on TRUNK.

I'm attaching some log files.
