    Description

      It appears that we don't use O_DIRECT in WriteEngine which probably means writes are getting put into the OS caches but are not being used by PrimProc which seems a waste.
      It might be better to use posix_fadvise() with POSIX_FADV_DONTNEED instead but more investigation is needed.
