/* Buffered repository tree.
* Observation: The in-memory representation of a node doesn't have to be the same as the on-disk representation.
* Goal for the in-memory representation: fast
* Goal for on-disk: small
*
* So to get this running fast, I'll make a version that doesn't do range queries:
* use a hash table for in-memory
* simply write the strings on disk.
* Later I'll do a PMA or a skiplist for the in-memory version.
* Also, later I'll convert the format to network order fromn host order.
* Later, for on disk, I'll compress it (perhaps with gzip, perhaps with the bzip2 algorithm.)
*
* The collection of nodes forms a data structure like a B-tree. The complexities of keeping it balanced apply.
*
* We always write nodes to a new location on disk.
* The nodes themselves contain the information about the tree structure.
* Q: During recovery, how do we find the root node without looking at every block on disk?
* A: The root node is either the designated root near the front of the freelist.
* The freelist is updated infrequently. Before updating the stable copy of the freelist, we make sure that
* the root is up-to-date. We can make the freelist-and-root update be an arbitrarily small fraction of disk bandwidth.
*
