> Related to FLINK-25414. In order to better debug Task being blocked in busy state, we can periodically enqueue a mailbox action and check how long it took for the task thread to execute such action. We can report this delay as task thread delay/mailbox delay. Would be helpful for debugging why unaligned checkpoints are taking so long to trigger/execute.
