> The checksum verification only works when {{BKDWriter}} fully reads one of its temp files, but today it opens a reader, seeks to one slice, reads that, and closes.
> But it turns out, on the full recursion from any given node in the tree, a given file is read once, fully, so if we just share the readers, then we can get checksum verification for these files as well.
> This is a non-trivial change ... I don't plan on pushing it for 6.0.
