/**
* Issue #756
*
* Partially sent buffers that timeout would cause the next request sent
* to appear inside the partially sent buffer, eventually leading to an
* InvalidReceiveException exception on the broker.
*
* This is easily triggered by:
* - decrease socket buffers
* - decrease message timeout
* - produce a bunch of large messages that will need to be partially sent
* - requests should timeout which should cause the connection to be closed
* by librdkafka.
*
* How do we monitor for correctness?
* - the broker shall not close the connection (but we might)
