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

We enabled the use of different stress branches, so we should be able to run it now. 

I'll restart the job that benedict ran: http://cstar.datastax.com/tests/id/01b714d8-5f32-11e5-a4e4-42010af0688f


I'll use [~benedict]'s stress branch from: https://github.com/belliottsmith/cassandra/tree/stress-report-interval

EDIT: test started: http://cstar.datastax.com/tests/id/ac36457a-67a0-11e5-8666-42010af0688f

> For smaller heap sizes G1 appears to have some throughput/latency issues when compared
to CMS. With our default max heap size at 8G on 3.0, there's a strong argument to be made
for having CMS as the default for the 3.0 release.
