Review comment:
I think I've found the culprit. It seems as if the `RestClient` does not
time out an established HTTP connection to the server. Due to that, it can
happen that we just established the connection when the `DispatcherProcess` is
killed. This apparently won't be noticed by Netty in time for the test to
finish. I'm still investigating why Netty cannot detect an unreachable remote
host.
