+** NOTES ON DATA STRUCTURE USED FOR N-WAY MERGES:
+**
+** As keys are added to the sorter, they are written to disk in a series
+** of sorted packed-memory-arrays (PMAs). The size of each PMA is roughly
+** the same as the cache-size allowed for temporary databases. In order
+** to allow the caller to extract keys from the sorter in sorted order,
+** all PMAs currently stored on disk must be merged together. This comment
+** describes the data structure used to do so. The structure supports 
+** merging any number of arrays in a single pass with no redundant comparison 
+** operations.
+**
+** The aIter[] array contains an iterator for each of the PMAs being merged.
+** An aIter[] iterator either points to a valid key or else is at EOF. For 
+** the purposes of the paragraphs below, we assume that the array is actually 
+** N elements in size, where N is the smallest power of 2 greater to or equal 
+** to the number of iterators being merged. The extra aIter[] elements are 
+** treated as if they are empty (always at EOF).
+**
+** The aTree[] array is also N elements in size. The value of N is stored in
+** the VdbeSorter.nTree variable.
+**
+** The final (N/2) elements of aTree[] contain the results of comparing
+** pairs of iterator keys together. Element i contains the result of 
+** comparing aIter[2*i-N] and aIter[2*i-N+1]. Whichever key is smaller, the
+** aTree element is set to the index of it. 
+**
+** For the purposes of this comparison, EOF is considered greater than any
+** other key value. If the keys are equal (only possible with two EOF
+** values), it doesn't matter which index is stored.
+**
+** The (N/4) elements of aTree[] that preceed the final (N/2) described 
+** above contains the index of the smallest of each block of 4 iterators.
+** And so on. So that aTree[1] contains the index of the iterator that 
+** currently points to the smallest key value. aTree[0] is unused.
+**
+** Example:
+**
+**     aIter[0] -> Banana
+**     aIter[1] -> Feijoa
+**     aIter[2] -> Elderberry
+**     aIter[3] -> Currant
+**     aIter[4] -> Grapefruit
+**     aIter[5] -> Apple
+**     aIter[6] -> Durian
+**     aIter[7] -> EOF
+**
+**     aTree[] = { X, 5   0, 5    0, 3, 5, 6 }
+**
+** The current element is "Apple" (the value of the key indicated by 
+** iterator 5). When the Next() operation is invoked, iterator 5 will
+** be advanced to the next key in its segment. Say the next key is
+** "Eggplant":
+**
+**     aIter[5] -> Eggplant
+**
+** The contents of aTree[] are updated first by comparing the new iterator
+** 5 key to the current key of iterator 4 (still "Grapefruit"). The iterator
+** 5 value is still smaller, so aTree[6] is set to 5. And so on up the tree.
+** The value of iterator 6 - "Durian" - is now smaller than that of iterator
+** 5, so aTree[3] is set to 6. Key 0 is smaller than key 6 (Banana<Durian),
+** so the value written into element 1 of the array is 0. As follows:
+**
+**     aTree[] = { X, 0   0, 6    0, 3, 5, 6 }
+**
+** In other words, each time we advance to the next sorter element, log2(N)
+** key comparison operations are required, where N is the number of segments
+** being merged (rounded up to the next power of 2).
