 Description   

When recovering a snapshot using queryable backup mode, it's possible for WiredTiger to do concurrent writes to the same file during recovery. This can only happen when there's cache pressure and WiredTiger triggers eviction threads.

The Cloud back-end was built on the assumption that writes to the same file are serialized during startup recovery.
