Revoke SHOWSTOPPER status. EAGAIN, retry, continue...

Same committer shipped a release with one well known broken platform within
days of proposing a showstopper for a platform. This specific platform is not
even universally broken, but only for maintainer mode builds, and same has
upvoted a backport which can't compile in maintainer mode. Confused yet?

It might also be why this well-reasoned patch gathered little review, since
it was parked in a more obscure place?
