+/**
+ * Implementation of {@link BatchRefUpdate} that uses the {@code packed-refs}
+ * file to support atomically updating multiple refs.
+ * <p>
+ * The algorithm is designed to be compatible with traditional single ref
+ * updates operating on single refs only. Regardless of success or failure, the
+ * results are atomic: from the perspective of any reader, either all updates in
+ * the batch will be visible, or none will. In the case of process failure
+ * during any of the following steps, removal of stale lock files is always
+ * safe, and will never result in an inconsistent state, although the update may
+ * or may not have been applied.
+ * <p>
+ * The algorithm is:
+ * <ol>
+ * <li>Pack loose refs involved in the transaction using the normal pack-refs
+ * operation. This ensures that creating lock files in the following step
+ * succeeds even if a batch contains both a delete of {@code refs/x} (loose) and
+ * a create of {@code refs/x/y}.</li>
+ * <li>Create locks for all loose refs involved in the transaction, even if they
+ * are not currently loose.</li>
+ * <li>Pack loose refs again, this time while holding all lock files (see {@link
+ * RefDirectory#pack(Map)}), without deleting them afterwards. This covers a
+ * potential race where new loose refs were created after the initial packing
+ * step. If no new loose refs were created during this race, this step does not
+ * modify any files on disk. Keep the merged state in memory.</li>
+ * <li>Update the in-memory packed refs with the commands in the batch, possibly
+ * failing the whole batch if any old ref values do not match.</li>
+ * <li>If the update succeeds, lock {@code packed-refs} and commit by atomically
+ * renaming the lock file.</li>
+ * <li>Delete loose ref lock files.</li>
+ * </ol>
+ *
+ * Because the packed-refs file format is a sorted list, this algorithm is
+ * linear in the total number of refs, regardless of the batch size. This can be
+ * a significant slowdown on repositories with large numbers of refs; callers
+ * that prefer speed over atomicity should use {@code setAtomic(false)}. As an
+ * optimization, an update containing a single ref update does not use the
+ * packed-refs protocol.
