Marking as release-blocker for Go 1.20 because darwin/amd64 is a first-class port and this failure mode seems to be new as of this cycle.

@neild Any opinion on whether this represents a release blocker?

Comment From: neild

I think this is occurring rarely enough that it's probably not new as of this cycle, and we just didn't notice any failures previously. So not a release blocker, although it does need fixing.
