Now we will run Persistence Inspector first. To perform out-of-order analysis, we
must use the -check-out-of-order-store option to the report phase. Listing 12-40
shows collecting the before and after data and then running the report.
Listing 12-40. Running Intel Inspector – Persistence Inspector with Listing 12-38
(writer) and Listing 12-39 (reader)
