> We have a single lock which is used for protecting access to shared
> coordinator state between the foreground thread and the background heartbeat
> thread. Currently, the onPartitionsRevoked callback is invoked while holding
> this lock, which prevents the heartbeat thread from sending any heartbeats.
> If the heartbeat thread is blocked for longer than the session timeout, than
> the consumer is kicked out of the group. Typically this is not a problem
> because onPartitionsRevoked might only commit offsets, but for Kafka Streams,
> there is some expensive cleanup logic which can take longer than the session
> timeout.
