 *  **Fix: improve parallelism of async requests.** OkHttp's Dispatcher had a
    misconfigured `ExecutorService` that limited the number of worker threads.
    If you're using `Call.enqueue()` this update should significantly improve
    request concurrency.

                directoryPath, leaseKey, directory);
            
            activeWatchers.put(directoryPath, handle);
            
            // Start async change notification
            startAsyncNotification(handle);
            
        } catch (Exception e) {
            log.error("Failed to start directory watching for: " + directoryPath, e);
        }
    }

```

As the path of each *path operation* has to start with `/`, like in:

```Python hl_lines="1"
@router.get("/{item_id}")
async def read_item(item_id: str):
    ...
```

...the prefix must not include a final `/`.

So, the prefix in this case is `/items`.

      get() = originalRequest.url.host

    val request: Request
      get() = originalRequest

    val call: RealCall
      get() = this@RealCall

    /**
     * Attempt to enqueue this async call on [executorService]. This will attempt to clean up
     * if the executor has been shut down by reporting the call as failed.
     */
    fun executeOn(executorService: ExecutorService) {

        // Message ID
        SMBUtil.writeInt8(1, buffer, headerStart + 24);
        // Reserved/Async ID
        SMBUtil.writeInt8(0, buffer, headerStart + 32);
        // Session ID
        SMBUtil.writeInt8(0, buffer, headerStart + 40);
        // Signature

/// tip | Dica

Perceba que aqui estamos utilizando o `open()` da biblioteca padrão que não suporta `async` e `await`, e declaramos a operação de rota com o `def` básico.

- Implement periodic cleanup of expired leases

### 9.2 Thread Safety
- Use concurrent data structures for lease storage
- Minimize lock contention in hot paths
- Async handling of lease breaks

### 9.3 Network Efficiency
- Batch lease requests when possible
- Implement lease key reuse for related files
- Optimize lease break acknowledgment timing
