--------------------------------
[~frm], [~mduerig] Would something like this work - [^OAK-7722.patch]? My
limited tests with
[https://github.com/apache/jackrabbit-oak/blob/trunk/oak-run/src/test/java/org/apache/jackrabbit/oak/run/DataStoreCommandTest.java]
are good.

> Currently, to collect all external blob references for the {{Mark}} phase of
> DSGC, we need to open the segment store in a read-write mode i.e. use
> FileStore instead of a ReadOnlyFileStore. The task is to implement the
> \{{collectBlobReferences}} method in the \{{ReadOnlyFileStore}}.
> The references being returned might be somewhat stale in this case but by not
> much.
