This PR detects these "hung" tasks and sets them back to `SCHEDULED` state so the scheduler can queue them up again. Closes: #19699 This is basically a resurrection of [PR19769](https://github.com/apache/airflow/pull/19769) which was [reverted](https://github.com/apache/airflow/pull/21556) because no one could reproduce/test it. We can reproduce the problem reliably in an isolated test environment, so we were able to test this fairly thoroughly. cc: @ephraimbuddy @kristoffern @kaxil --- **^ Add meaningful description above** Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/main/CONTRIBUTING.rst#pull-request-guidelines)** for more information.
