+# 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.
