> If a source task blocks during its {{stop}} method, the herder thread will also block, which can cause issues with detecting rebalances, reconfiguring connectors, and other vital functions of a Connect worker.
> This occurs because the call to {{SourceTask::stop}} occurs on the herder's thread, instead of on the source task's own dedicated thread. This can be fixed by moving the call to {{SourceTask::stop}} onto the source task's dedicated thread and aligning with the current approach for {{Connector}}s and {{SinkTask}}s.
