I published an article and requested it.  According to ds, there are a bunch of
queries that would ideally be rolled into one for performance reasons.  For
example, there are 7 queries that each select a different column from the same
table:

select ao.object_id as column0,
       ao.default_domain_class as column1
from content_types ct,
     acs_objects ao
where ao.object_id = ct.type_id and ? = ct.type_id


    BINDS: {1=111}

	 
15	1 ms	521234698	

select ao.object_id as column0,
       ao.display_name as column1
from content_types ct,
     acs_objects ao
where ao.object_id = ct.type_id and ? = ct.type_id


    BINDS: {1=111}

	 
16	1 ms	521234698	

select ao.object_id as column0,
       ct.object_type as column1
from content_types ct,
     acs_objects ao
where ao.object_id = ct.type_id and ? = ct.type_id


    BINDS: {1=111}

and so on.
