> For intermittent checkpoint failures it is desirable to have a mechanism to
> avoid restarts. If, for example, a transient S3 error prevents checkpoint
> completion, the next checkpoint may very well succeed. The user may wish to
> not incur the expense of restart under such scenario and this could be
> expressed with a failure threshold (number of subsequent checkpoint
> failures), possibly combined with a list of exceptions to tolerate.
