Research direction
Investigate the CachingDirectoryLister class to understand the current list method. Implement a timeout mechanism using Java's CompletionService or Future with timeout. Ensure that the timeout does not leave resources in an inconsistent state. Look for existing timeout patterns in the Trino codebase for consistency.
