Prior to this update, the mpathpersist utility sometimes attempted to wait on threads that it did not create. As a consequence, mpathpersist terminated unexpectedly if there was a registration conflict on one of the paths. With this update, mpathpersist now waits only for threads that it creates. As a result, mpathpersist no longer crashes in this situation.
