I think that should not happen, at least not as long as you only do readonly accesses to UBI. In this case scrubbing work may be added to the list of pending works, but that list is never processed. This can change though if you create/delete volumes or if you write to volumes. In this case produce_free_peb() or ubi_wl_flush() may be called which both process the list of pending works. I hope that helps. If in doubt you should familiarize with the code yourself.
