open_lock_file retries while the open fails with raw os error 32 (cfg(windows) only), as lock_exclusive and lock_shared already wait on the lock itself. The try entry opens once and maps a sharing violation to Ok(None). Helpers take the open closure and busy predicate so Linux tests drive them with fakes.
