+          (where c{i} are constants).
+          Our goal is to produce a SEL_ARG graph that represents intervals:
+          
+          ($MIN<t.key<c1) OR (c1<t.key<c2) OR (c2<t.key<c3) OR ...    (*)
+          
+          where $MIN is either "-inf" or NULL.
+          
+          The most straightforward way to handle NOT IN would be to convert
+          it to "(t.key != c1) AND (t.key != c2) AND ..." and let the range
+          optimizer to build SEL_ARG graph from that. However that will cause
+          the range optimizer to use O(N^2) memory (it's a bug, not filed),
+          and people do use big NOT IN lists (see BUG#15872). Also, for big          
+          NOT IN lists constructing/using graph (*) does not make the query
+          faster.
+          
+          So, we will handle NOT IN manually in the following way:
+          * if the number of entries in the NOT IN list is less then 
+            NOT_IN_IGNORE_THRESHOLD, we will construct SEL_ARG graph (*)
+            manually.
+          * Otherwise, we will construct a smaller graph: for 
+            "t.key NOT IN (c1,...cN)" we construct a graph representing 
+            ($MIN < t.key) OR (cN < t.key)  // here sequence of c_i is
+                                            // ordered.
+
+          A note about partially-covering indexes: for those (e.g. for 
+          "a CHAR(10), KEY(a(5))") the handling is correct (albeit not very
+          efficient):
+          Instead of "t.key < c1" we get "t.key <= prefix-val(c1)".
+          Combining the intervals in (*) together, we get:
+          (-inf<=t.key<=c1) OR (c1<=t.key<=c2) OR (c2<=t.key<=c3) OR ...
+          i.e. actually we get intervals combined into one interval:
+          (-inf<=t.key<=+inf). This doesn't make much sense but it doesn't
+          cause any problems.
