I was actually looking through the code to find something like this but it
seems that every class does this locally for now. Global exit codes make sense
though - also for documentation
> Set uncaught exception handler for Netty threads

> Reporter: Ufuk Celebi
> Priority: Minor

> We pass a thread factory for the Netty event loop threads (see
> {{NettyServer}} and {{NettyClient}}), but don't set an uncaught exception
> handler. Let's add a JVM terminating handler that exits the process in cause
> of fatal errors.
