22:25 | Change the recursive common table expression algorithm to use a queue instead of a pair of tables. Runs about 25% faster on the sudoku solver query. The OP_SwapCursors opcode is no longer required. The current implementation uses just a fifo, but the plan is to change it into a queue that will support ORDER BY and LIMIT in a recursive query.
