Currently, we don't reschedule stream in this case, since we
don't retain enough information to do that
(descendant_last_cycle we used to schedule it). This means new
weight is only applied in the next scheduling, and if weight is
drastically increased, library is not responding very quickly.
If this is really an issue, we will do workaround for this. */
