Description:
Info
We set the storage stats that we want to report in curop here with the assumption that computeOperationStatisticsSinceLastCall() is called at the end of every operation. However, it is possible not to meet these + this conditions resulting in some operations not calling computeOperationStatisticsSinceLastCall(). When we eventually do call the method on a slow op we want to log, _sessionStatsAfterLastOperation can be stale and we end up reporting storage stats that include prior operations.
