4db38a7092 All regression tests now pass with the new bounded-memory sort code. 
There is still lots of opportunity for optimization, however. (CVS 2654)

0342b1f542 Sorting is now done using a sorting index rather than loading the entire 
result set into memory and doing a merge sort.  The old merge sort technique
was a carry-over from SQLite version 1.  The new method uses a bounded amount
of memory and scales to much larger result sets.  There are still errors:
some 39 regression tests fail. (CVS 2653)
