Hm, I think 0ba06e0 is actually the relevant change here? Though
40cfe86 was a necessary cleanup fix.

I'm too tired to dig in the buildfarm database to be sure, but my
impression is that the failure rate is much-better-but-not-zero.
So I'd support back-patching those two commits, but I'm not sure
if that's the end of the conversation.
