> We have several instances in our system test services where we invoke
> Thread.join() in the stop_node() function to stop the service. It probably
> makes sense to use a timeout in join() to ensure that the process eventually
> has a chance to do unclean shutdown when the process becomes unresponsive. We
> have seen several cases in our daily runs (with the verifiable consumer in
> particular) where the process seems to hang on this join.
