The point is, it's not just one select. For example:
Select field1, field2, field3, field4, deleted() as ldeleted1 ;
  from table1 into cursor1 where field1 = x
Select field1, field2, field3, deleted() as ldeleted2 ;
  from table2 into cursor2 where field1 = x
select a.*, b.* from cursor1 a, cursor2 b into cursor3 where a.field1 = b.field1
Now do whatever with cursor3 using ldeleted1 and ldeleted2 if necessary.

Even with the intermediate steps, as long as it's optimised and I don't have to worry about a deleted() tag, it's fast.
