@jhpratt fyi the hang on #160682 (comment) seems real, I haven't had time to debug it yet

[jhpratt]

@bors p=0

In case the current PR being tested fails. Set back once it's figured out.

I saw it was a timeout; is that not typically spurious?

[JonathanBrouwer]

Both the try job and test job stalled on the same job so I expected it to be real

[JonathanBrouwer]

Could just be very unlucky tho, so let's see what the try job on this rollup does

[jhpratt]

Hmm...well this rollup is here even if something else has to be scheduled ahead of it. We'll see what happens with the current PR.

This rollup was thus unapproved.

Since the try jobs succeeded here I guess we did just get unlucky twice on the same job, lol
