That's not really a challenge to the buildbot operator, though - the
buildbot will continue just fine afterwards, right?

For some reason, the test suite stopped producing output, and
eventually, the buildbot decided to kill the build process.
Most likely, the machine ran severely out of memory, so everything
stopped working.
