Half the time it seems thinking about context manager means your code
is already going down the wrong route.

In this case, it takes the problem of "doing this results in 9 ssh
connections that then hang around for a bit" and turns it into "doing
this seems to work but is massively slow because it's repeatedly
creating one ssh connection after another".

What seems to be needed instead of prompt cleanup is proper transport reuse.
