> {{KafkaAdminClient#timeoutCallsInFlight}} does not work as expected. The
> original idea was that this function would time out a call by closing the
> associated socket. Then the following {{NetworkClient#poll}} call would
> trigger the call to be removed. However, it turns out that it sometimes
> takes time for the {{NetworkClient#poll}} call to return the disconnection
> events. This leads to the call lingering for a while, causing us to
> repeatedly disconnect connections to that node.
