... To not try instantly, but also not to wait forever to retry. Also, the maximum delay is also now the proper setting to cause the attempt to exit, and is only set to 10 seconds, with a fairly tight interval for retries to occur within. This change also doesn't abort retries for releasing a node lock and updating a node, both actions if they halt due to the close out of a task, can be catastrophic to the underlying operation and state, because internal actions around locking can't be retried with a long interval, otherwise things break in very bad ways.
