606	backupdb: add directory cache	warner		"We can speed up the #598 ""tahoe backup"" command even more by caching tahoe-side read-only directory contents. At the moment, we have to read every Tahoe directory to find out whether we can share it with a new backup or not. With a table in the backupdb that maps dircap to hash of its contents, we can avoid those reads, and get rid of almost all of the network IO involved in a null backup.
