Cassandane depends on presence of core files to detect/report process crashes, so if these aren't being generated (e.g. due to ulimit -c 0), it can't report crashes. And developers depend on core files not being truncated, so they can debug the damn things!
So we need a test that specifically does something that will always dump a large core, then check that the core file is created and is not truncated. If this test fails, then other tests' "success" results might be false.
