+  * multiple fragments per object (with configurable size.. maybe 1 or 2 mb default?)
+    * read path should be totally generic (handle any fragment pattern)
+    * write path should ideally tolerate any fragment pattern, but only generate a fixed layout (since the tunable may be changed over time).
+  * rocksdb: use db_paths (db/ and db.bulk/ ?)
+  * rocksdb: auto-detect use_fsync option when not xfs or btrfs
   * hobject sorting
