As far as I understand, verification in the multi-threaded (num_jobs > 1) case is neither supported nor recommended.
-- I wonder if it also holds for the case of a multiple-threaded job being run against a partitioned (using FIO's offset split machinery) device, with thread per partition. Partitioning like this should very much avoid any inter-thread overlap, and seems to be safe to run in verify mode. I will appreciate a comment on whether the simple reasoning above holds, or something extra still needs to be done.
