And so far we assumed that consumer->filter() is "stable" and never changes its mind. Perhaps this is fine, but I am not sure. May we need need some interface to add/del the task.

But if we change the rules so that ->filter() or ->handler() itself can return the "please remove this bp from ->mm" then perhaps it makes more sense for the filtering. Again, not sure.
