- * Record all btree blocks seen while iterating all records of a btree.
- *
- * We know that the btree query_all function starts at the left edge and walks
- * towards the right edge of the tree.  Therefore, we know that we can walk up
- * the btree cursor towards the root; if the pointer for a given level points
- * to the first record/key in that block, we haven't seen this block before;
- * and therefore we need to remember that we saw this block in the btree.
- *
- * So if our btree is:
- *
- *    4
- *  / | \
- * 1  2  3
- *
- * Pretend for this example that each leaf block has 100 btree records.  For
- * the first btree record, we'll observe that bc_levels[0].ptr == 1, so we
- * record that we saw block 1.  Then we observe that bc_levels[1].ptr == 1, so
- * we record block 4.  The list is [1, 4].
- *
- * For the second btree record, we see that bc_levels[0].ptr == 2, so we exit
- * the loop.  The list remains [1, 4].
- *
- * For the 101st btree record, we've moved onto leaf block 2.  Now
- * bc_levels[0].ptr == 1 again, so we record that we saw block 2.  We see that
- * bc_levels[1].ptr == 2, so we exit the loop.  The list is now [1, 4, 2].
- *
- * For the 102nd record, bc_levels[0].ptr == 2, so we continue.
- *
- * For the 201st record, we've moved on to leaf block 3.
- * bc_levels[0].ptr == 1, so we add 3 to the list.  Now it is [1, 4, 2, 3].
- *
- * For the 300th record we just exit, with the list being [1, 4, 2, 3].
