Description

We should update the docs to explain that calling KafkaStreams#close() within the UncaughtExceptionHandler-callback might result in a deadlock and one should always specify a timeout parameter for this case.

As an alternative to avoid the deadlock, setting a flag in the handler and calling #close outside of the callback should also work.
