python3-async-timeout binary package in openKylin Nile V2.0 amd64

 The context manager is useful in cases when you want to apply timeout
 logic around block of code or in cases when asyncio.wait_for() is
 not suitable. Also it's much faster than asyncio.wait_for()
 because timeout doesn't create a new task.
 .
 Example:
 .
  with timeout(1.5):
      yield from inner()
