A finalizer task (exclusive resource lock) can start before sibling tasks (shared resource lock) have completed if they are blocked on a separate exclusive resource. In the Redis worker, this bypasses FIFO ordering because the sibling's shared resource is never added to blocked_shared when the blocking reason is its exclusive resource.
