            Description

            In the past, WiredTiger has kept metadata pinned in cache. That prevents any eviction from the metadata table, including cleaning up of tombstones. As a result, workloads that create and drop many tables can grow the metadata table in cache without bound.

            Once the metadata table grows larger than the cache size, other operations are blocked.
