+   1. Non-recursive, using an explicit stack of pointer that store the

+      of space required to store an array of MAX_INT is allocated on the
+      stack.  Assuming a 32-bit integer, this needs only 32 *
+      sizeof(stack_node) == 136 bits.  Pretty cheap, actually.
+
+   2. Chose the pivot element using a median-of-three decision tree.
+      This reduces the probability of selecting a bad pivot value and
+      eliminates certain extraneous comparisons.
+
+   3. Only quicksorts TOTAL_ELEMS / MAX_THRESH partitions, leaving
+      insertion sort to order the MAX_THRESH items within each partition.
+      This is a big win, since insertion sort is faster for small, mostly
+      sorted array segments.
+
+   4. The larger of the two sub-partitions is always pushed onto the
+      stack first, with the algorithm then concentrating on the
+      smaller partition.  This *guarantees* no more than log (n)
+      stack size is needed (actually O(1) in this case)!  */
