Please also remove the calls to minor_collection_begin() and 
minor_collection_end(), otherwise this goes from a trivial "remove dead 
code" fix to a change in the actual logic. If these calls are needed at 
some point in the future (which I doubt given that CMS is deprecated and 
will likely go away soon), they can be added then.

cheers,
