Rather than rely on ElasticsearchUncaughtExceptionHandler, it is safer
to use the JVM's built-in support for terminating the process on OOM.

Only caveat is a change of exit code from 127 to 3. Feels hardly breaking, since
we do not document the exit codes.

I sent you a link by Slack from the Cloud codebase where these error codes are relied upon! Every change breaks someone’s workflow.
