    initial v1  
    77I guess it gives a performance boost because we will want some of the blocks in that arbitrary set, and so pre-reading something is better than pre-reading nothing - we get reads for free while other stuff is going on.

    9 But I think this should be calling `block_to_cursor()` while it descends the tree, and then instead does the pre-read instead at the lowest level (which might not be the leaf level necessarily, but there's not much point iterating after we stop reading blocks).
