Windows job intermittently fails during git clean: "Unexpected termination of the channel"

[SethTisue]

it's possible this is somehow related to an earlier, different problem where the same thing would just hang: #203 . but this behavior is different, so I'm making a fresh ticket

seen at e.g.

 > git clean -fdx # timeout=10
