> We keep {{SSTableReader}} references for the duration of the repair to anti-compact later,
and their tidier keep references to cache keys to be invalidated which are only cleaned up
by GC after repair is finished. These cache keys can accumulate while repair is being executed
leading to OOM for large tables/keyspaces.
> Heap dump attached.
