-# The problem in ticket #2640 was that the query optimizer was 
-# not recognizing all uses of tables within subqueries in the
-# WHERE clause.  If the subquery contained a compound SELECT,
-# then tables that were used by terms of the compound other than
-# the last term would not be recognized as dependencies.
-# So if one of the SELECT statements within a compound made
-# use of a table that occurs later in a join, the query
-# optimizer would not recognize this and would try to evaluate
-# the subquery too early, before that tables value had been
-# established.
