> When I run an in-process instance of KafkaServer, send a message through it,
> then call shutdown(), some threads never exit and the process hangs until the
> process is killed manually. The same scenario does not result in a hang on
> 0.8.0. The hang happens when calling both shutdown() by itself as well as
> shutdown() and awaitShutdown() together. I have seen similar behavior
> shutting down a deployed kafka server as well, but haven't had time to
> diagnose whether or not it is the same symptom.
