## Workarounds

1. **** (95% success)
   ```
   try: await asyncio.sleep(10) except asyncio.CancelledError: raise
   ```
2. **** (80% success)
   ```
   await asyncio.shield(asyncio.sleep(10))
   ```

## Dead Ends

- **** — Blocks the event loop and defeats the purpose of asyncio. (90% fail)
- **** — May lead to resource leaks and inconsistent state. (70% fail)
