We eventually have no zombies, at least the zombie detector does not find anything, but meanwhile on memory limited EC2 instances I'm seeing tests killed by the OOM killer, very likely meaning that previous tests are still in the process of shutting down and are hanging around in the process table, consuming RAM, VMM, etc. I didn't see this before the switch to Hadoop 2 as default. I'm not suggesting we switch back. I wonder if there is anything that can be done to wait for the forked process to actually terminate? Is this a Surefire bug?
