@bradfitz – is there a way to grep the builder's outputs? As far as I can see this is only flaky in win 386, but that's based on random sampling failures. I can't repro it locally in linux x64 yet.

Taking a look at the code now, but I'm not too familiar with it so might take a while.

@aclements has such powers. See x/build/cmd/fetchlogs. Austin also has more tools (not checked in?).

Fetchlogs doesn't grab the subrepos and findflakes doesn't know how to deal with them either. :/

That's (at least partially) #35515.

Fortunately, context is now in the standard library. Unfortunately, TestDeadline is still a bit flaky.
