When using -cut-over-exponential-backoff with -default-retries > 62, the sleep interval will overflow and there will be no further useful delays between retries.

This is caused by math.Exp2(62) exceeding int64 limit. As the negative value is smaller than the maximum, the time.Sleep is executed with nanosecond delays.
