-// Implements a naive mark-and-sweep tracing garbage collector.
-//
-// The algorithm is basically as follows:
-// 1. Read (and filter) all index entries ("pointers")
-// 2. Mark each integrity value as "live"
-// 3. Read entire filesystem tree in `content-vX/` dir
-// 4. If content is live, verify its checksum and delete it if it fails
-// 5. If content is not marked as live, rimraf it.
