> Issue Type: Bug

> Running a nodetool repair -pr --full on a keyspace with a few hundred tables
> will cause a direct memory OOM, or lots of heap pressure with
> use_offheap_merkle_trees: false. Adjusting repair_session_space_in_mb does
> not seem to help. From an initial look at a heap dump, it appears to node is
> holding many _remote_ trees in memory.
