heh, I actually realized when I scrolled through the other day that this comment no longer applies. the `ukeysort` should be sufficient. I tried to stay away from using `riak_core_bucket_props:merge` since its indirectly under test. Maybe a little too paranoid but i think `ukeysort` is sufficient. fwiw, the reason the comment lingers is when I wrote this there was no call to `ukeysort` and the test inevitably failed. I fixed the test but forgot about the comment.
