Deadlock upon calling `await client.abort()`

I'm trying to implement abort download as described in [Advanced download and upload, abort, restart](https://aioftp.readthedocs.io/client_tutorial.html#advanced-download-and-upload-abort-restart). Following the example, I find that `await client.abort()` deadlocks, but if my code first calls `stream.close()`, then it can call `await client.abort()` without deadlock. Are these two lines mixed up in the example?
