> Recently implemented close( withTimeout ) for streams does not work under load conditions
in the multi-threaded KStream application.
> Where there are more consuming threads and there many messages in stream, then close
( withTimeout ) does not work. 
> 1. Timeout is not respected at all and
> 2. application is hanging in some streaming chaos. Theoretically threads are working
- they are busy with themselves, so the app cannot end, but they are not processing any further
messages.
