> The TarMK would benefit from periodic "compact" operations that would traverse and recreate
(parts of) the content tree in order to optimize the storage layout. More specifically, such
compaction would:
> * Optimize performance by increasing locality and reducing duplication, both of which
improve the effectiveness of caching.
> * Allow the garbage collector to release more unused disk space by removing references
to segments where only a subset of content is reachable.
